Select all the expressions that are equivalent to 16x - 12 - 24x + 4 1) 4 + 16x - 12(1 + 2x)
2) 40x - 16
3) 16x - 24x - 4 + 12
4) -8x - 8

(1) and (4)

Step-by-step explanation:

4 + 16x - 12(1 + 2x) = 4 + 16x - 12 - 24x

4 + 16x - 12 - 24x = 16x - 12 - 24x + 4

- 24x + 16x = -8x

- 12 + 4 = -8

Which creates -8x - 8
