First you always start from inside and move out.
so -7[-2x – (3x + 8) + 5] – 3x + 7 becomes -7[-2x - 3x - 8 + 5] - 3x + 7 by multiplying everything in the paranthesis by -1.
Then combine like terms in the brackets giving you -7[-5x - 3] - 3x + 7.
Now distribute the -7 which leaves you with: 35x + 21 - 3x + 7.
Finally combine like terms. And the answer is: 32x + 28 or 4(8x + 7).

-7%28-2x-%283x%2B8%29%2B5%29-3x%2B7

= -7%28-2x-3x-8%2B5%29-3x%2B7 First remove the innermost brackets.

= -7%28-5x-3%29-3x%2B7 Simplify within bracket.

= 35x%2B21-3x%2B7

= 32x + 28 = 4(8x+7). Answer. I dont know where you have gone wrong to get negative 4 in the answer.
