Answer:
x = 6
Explanation:
First, separate the problem into

Then, Subtract 9 from both sides of the equation.

Simplify.

Multiply 3 to each side, which will give you -2x = 4x - 36
Subtract 4x from each side -2x - 4x = 4x - 36x - 4x
Combine like terms: -6x = -36
Divide both sides by -6
Your answer should be 6
