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.
