Question

Solve x∕10 = –7.

Question 7 options:

A)

x= –17

B)

x = 3

C)

x = –0.7

D)

x = –70

Answer 1

D) x = 70

10 (x/10) = -7 (10)
Multiply 10 on both sides.

x = -70

Answer 2

D) x = -70

Explanation:

You can do the opposite to find out what x equals. The opposite of division is multiplication. So, -7 · 10 = -70.

Check your answer by plugging in -70 for x. So -70/10 = -7. This is correct which means x = -70
