Answer:
-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:)
