For this problem, we will combine the like terms. Like terms are the ones that contain the same variables raised to the same power. For example: 2x is a like term of 3x.
In this equation, 11x, -6x, and 3x are like terms. We will combine those first.
11x+3x-6x+9 -> All of our like terms are grouped together
14x-6x+9
8x+9
