Which of the following equations could be used to solve the given equation?

9x + 26 + 7x - 17 = 2x + (-3x) + 5x
16x + 9 = 0
16x + 9 = 4x
16x + 11 = 4x

Well, lets first start off with combining like terms.

9x + 26 + 7x - 17 = 2x + (-3x) + 5x

9x + 7x + will give you 16x, and 26 - 17 will give you 9. Therefore, the first part of the equation is 16x + 9.

On the other side, you can combine all three terms (2x + 5x - 3x), which will give you 4x.

Using the above steps, you can figure that the answer is 16x +9 = 4x
