Step-by-step explanation:
In order to combine like terms, you have to isolate x and y from one side of the equation.

<u>First, thing you do is remove parentheses.</u>

<u>Solve.</u>
<u>Then, you combine like terms.</u>

<u>Add/subtract the numbers from left to right.</u>
-8z+3.5z=-4.5z
<u>Rewrite the problem down.</u>

<u>Solve.</u>
4.5-1.5=3

- <u>Therefore, the correct answer is 7y+3-4.5z.</u>
I hope this helps, let me know if you have any questions.
The estimate of the problem would be 1/4 because 6/8- 1/2 you would get 1/4.
~Good Luck!~
