#3x+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 #5x# 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!
