Question

Need help and also need the steps

Answer 1

-9

Explanation:

- 12 = 20 + 9x - 6x - 5 is -9

Answer 2

-13.5 = x

Explanation:

-12=20+9x-6x-5

First of all, combine like terms: 20-5 and 9x-6x = -12=15-2x

Next subtract 15 from both sides to leave -2x by itself.

-12 = 15 - 2x

-15 -15

-27 = -2x Finally divide both sides by -2 to leave x by itself.

-27/2 = -13.5 and -2/-2

-13.5 = x

Hope it helps:)
