Once again, you could say the coefficient on 7y is 7. Where there is the 3y - 2y I can replace that with y: x + y + (4z - 3z).
Explanation Detail steps. We're going to simplify this expression together putting to use our new knowledge of how to combine like terms. I cannot answer your question. Example 3: Check whether the two expressions and equivalent. Equivalent Expressions.
Subtracting a z is the exact same thing as subtracting 1z. Here, the terms and are like terms. What was the coefficient right here on this negative z? So, add their coefficients.. Also, and can be combined to get. And so you could just say, oh, I had to just add the coefficients. The word "onesie" strikes a part of my brain because I have very young children, but that's a different type of onesie. Now let us consider some expressions that include variables, say. And that's OK, and there's nothing wrong with that. And the coefficient on this subtracting the 2x, the coefficient here is negative 2, and we had to add the coefficients. Explain your answer. And then you could see, oh, yeah, you definitely did add the two coefficients, the 8 and the negative 1. 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. 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? Let's just think about it, step by step.
Step 2: Now click the button "Submit" to get the equivalent expression. I understand where the 4 is from but where did the 1 come from? So this part right over here is going to simplify to 10y.
