You can't combine any further as p can be anything and there are four of them. So i'm confused with this question: Combine the like terms to create an equivalent expression. And it might help if we were to actually reorder the terms in this expression. No, the number wont get more negative. Here is one perspective on this Ted Talk - "Why is X the unknown, (12 votes).
Step 2: Now click the button "Submit" to get the equivalent expression. So, your problem is actually: 4t-1t+2. 4p+3 since you can combine the +6 and the -3 into +3. Does the answer help you? How would, for example 2z-7-1 = 2z + 8(4 votes). First, it was in the right order and then Sal changed the order to gather same species. And finally the z terms to get x + y + z which is exactly equal to the original expression, that is: 2x + 3y + 4z - x - 2y - 3z = x + y + z. Now we'll just think it through. Which expression is equivalent to 3b 2r 4b r e. Gauth Tutor Solution. Okay now I've watched this and I'm still a little confused(4 votes). Example 3: Check whether the two expressions and equivalent. Provide step-by-step explanations. Still have questions?
Crop a question and search for answer. And so you could just say, oh, I had to just add the coefficients. That is, the expressions are equivalent except when. I don t get what minus one z from 8 z and it equals 7 how? And that's OK, and there's nothing wrong with that. Which expression is equivalent to 3b 2r 4b r.e. And you might say, hey, wait. But once again, common sense tells you if you have 8 of something, and you take away 1 of them, you have 7 of that something. BYJU'S online equivalent expression calculator tool makes the calculations and simplification faster and it displays the equivalent expression in a fraction of seconds. That is, they are equivalent expressions.
The mathematical property which allows us to do so is the commutative property of addition, which says, essentially, that, "when adding things up, order doesn't matter, " so x+y+z=x+z+y=z+y+x etc. Subtracting a z is the exact same thing as subtracting 1z. Unlimited access to all gallery answers. Which expression is equivalent to 4y 2. Question: Write the equivalent expression for the given expression: 3x+9. These right over here are the coefficients. Explain your answer.
The expression can be rewritten as. Then I have plus 7y plus 3y. Take 3 outside from the expression, we get, = 3(x+3), which is called the equivalent expression. Now let us consider some expressions that include variables, say. Ask a live tutor for help now. What was the coefficient right here on this negative z? We added the coefficients-- 7 plus 3-- to get 10y. And then finally, you have a plus 5. The calculator works for both numbers and expressions containing variables.
We solved the question! So we can take 5 x's and take away 2 x's. We can't think about merging the x's and the y's, at least not in any simple way right now, because that, frankly, wouldn't make any intuitive sense. Example 4: Consider the first expression for any non-zero values of the variable. Why is X the most common letter used in math? Well you are just add the X's to the numbers like this (the first number is the coefficient btw)2x +4X = whatever the answer would be. We have a hairy-looking expression here.
The coefficient on 3y is 3. The first expression is the sum of 's and 's whereas the second one is the sum of 's and 's. So this part right over here is going to simplify to 10y. It's much more if you've got 7 of something, you add another 3 to that something, you've got 10 of that something. I understand where the 4 is from but where did the 1 come from? You have to make sure that you're adding and subtracting the same things. Well, I'm going to be left with 3 x's. If I have 7 of something, and I were to add 3 more of that something, well, then, I'm going to have 10 of that something. And then you could see, oh, yeah, you definitely did add the two coefficients, the 8 and the negative 1. So the equation becomes this: -4q +8q +10. Here, the terms and are like terms. Therefore, the two expressions are not equivalent.
I thought the answer is - 12q + 10. bcoz the the rule is "negative minus negative" the number will be just get more negative? Where there is the 3y - 2y I can replace that with y: x + y + (4z - 3z). If I've got 8 of something and I take away 1 of them, I'm going to have 7 of that something. Can we actually combine terms like that? So let me put all the x terms first. Consider the expressions and. But I really want to emphasize the intuition here.
How to Use the Equivalent Expression Calculator? Let me write that word down-- coefficient. If I have 5 x's and I were to take away 2 x's, is how many x's am I going to be left with? Remember, a variable without a visible number in front has a coefficient of 1. So if I have 2x + 3y + 4z - x - 2y - 3z, I can rearrange that to 2x - x + 3y - 2y + 4z - 3z. If you have 5 of something, you take away 2 of that something, you are left with 3 of that something. I don't see any number out front of the z. Or maybe you are upset because someone (a teacher or parent) is making you do this, and you just protest against others telling you what to do. We can re-group the right side of the equation to or or some other combination. So I have 5x-- that's that term-- minus 2x. Want to join the conversation? Khan has a lot of good content that help a lot of other people, so you have to figure why it does not help you. So you're the 5 or the negative 2 in this case. Now let's look at the z's.
Like for example 4p +6 −3 how would you solve that? I am confused where did the (4-1) come from? The procedure to use the equivalent expression calculator is as follows: Step 1: Enter an algebraic expression in the input field. Combine the 2 terms containing "t" by subtracting their coefficients and you get 3t+2. 5 of anything minus 2 of that same thing, you're going to be left with 3 of that thing. Check the full answer on App Gauthmath. Gauthmath helper for Chrome. Created by Sal Khan. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. And your goal is to try to simplify it as much as you can.
