Answer 5

Let's break it up. You have \[-2-7(1-y)\] as your starting equation. Now, observe that only -7 is next to the parentheses [round brackets], and only -7 is being multiplied by everything WITHIN the bracket, i.e all the individual terms.

Answer 7

so \[-2 -7(1) - 7(-y)\] which gives \[-2-7+7y\]

Answer 8

\[-2-7\] is equal to \[-9\]..

Rearrange the terms and you have \[7x-9\].
