Question

8x-8=-72 how would I find the answer

Answer 1

8x-8=72
+8 +8

8x=80

8x/8 80/8

X=10

1st step do the opposite of subtracting which is adding so add 8 on each side like shown above .

2nd step after adding and canceling you bring down 8x=80

3rd step you need to get x by itself so divide 8 in each side shown above

4th step the answer is X=10

Answer 2

-8 + -8 + -8 + -8 + -8 + -8 +-8 +-8 = -72
that's one way to solve it.
