Answer:

-8x + 9

Explanation:

(–5x + 7) – (3x – 2) has a hidden coefficient. Because the second set of brackets is subtracted, everything is multiplied by -1:

(–5x + 7) –1(3x – 2).

This can then be written as -5x + 7 - 3x + 2, as the symbols flip in the second set of brackets.

Then you collect the terms to get -8x + 9.
