# Question 3d946

$3 x + 1$

#### Explanation:

To solve, let's simplify this into two separate equations:

11x-?=6x

9-?=8

We can solve for ? in both equations, and we will get $5 x$ in the first and $1$ in the second.

Therefore, once we consider the entire given equation, (11x + 9) − (?) = 6x + 8, the answer is simply the sum of the two ?s that we found above. Therefore, the answer is ?=5x+1#.

I hope that helps!
