Question

6 − x = −12 A) -18 B) -6 C) 0 D) 18

Answer 1

Answer: D) 18

Step-by-step explanation:

6 - x = -12

Subtract 6 from both sides.

-x = -18

Divide by -1 on both sides so as to isolate x.

x = 18

Answer 2

Answer:

D. 18

Step-by-step explanation:

The first thing you need to do is subtract 6 from both sides. This makes it cancel out on the left, since 6 - 6 = 0, and subtract 6 from -12:

6 − x = −12

-6        - 6

________

-x = -18

Then divide both sides by -1, because there's a negative sign (-) in front of the x, meaning there's like an invisible 1 there:

-1x = -18

x = 18
