Answer:
x = -3
Explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 6 from both sides:
6x + 6 (-6) = -12 (-6)
6x = -12 - 6
6x = -18
Isolate the variable, x. Divide 6 from both sides:
(6x)/6 = (-18)/6
x = (-18)/6
x = -3
x = -3 is your answer.
