4*8x is 32x

4*-2 is -8


32x-8=72


Move eight to the other side as a positive number


32x=80


Divide both sides by 32


Therefore x is equal to 2.5

Answer:-2

Step-by-step explanation:

4(8x - 2)=-72

Divide both sides by 4

4(8x - 2) ➗ 4=-72 ➗ 4

8x-2=-18

add 2 to both sides

8x-2+2=-18+2

8x=-16

Divide both sides by 8

8x ➗ 8=-16 ➗ 8

x=-2
