Answer:
x = -9
Step-by-step explanation:
You are solving for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 7 from both sides:
2x + 7 (-7) = -11 (-7)
2x = -11 - 7
2x = -18
Next, divide 2 from both sides:
(2x)/2 = (-18)/2
x = -18/2
x = -9
x = -9 is your answer.
