Simplify this expression:

-7w + (-6) + 5 + (-9w)

• -2w - 1

• -16w - 11

• -16w - 1

• -2w + 11

Simplify this expression

-6x + 7y + (-5x) - 9 - 5y

• -9xy -9

• -11x + 2y -9

• -1x + 2y -9

• -11x - 2y -9

4x - 7 = 21

• x = 12

• x = 7

• x = 24

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5
