Answer 2

First, start working on the inner parentheses.
You need to distribute the negative sign by x + 7.

Answer 3

A negative sign outside parentheses is the same as a -1 outside parentheses.
Use the distributive property to multiply -1 by x + 7

Answer 4

so its 7?

Answer 5

No.
This is how you do it.

Answer 6

\(-2[9 - (x + 7)] \)

First, distribute the negative outside the parentheses:

\(=-2[9 - x - 7)]\)

Now combine the 9 and the -7 inside the parentheses.

Answer 7

\(= -2[2 - x]\)

Now we distribute the -2:

\(= -4 + 2x\)

\(= 2x - 4\)
