Answer:
x = -3/2
Step-by-step explanation:
Starting from the simplified form, we can subtract 22x to get ...
6x -56 = -65
6x = -9 . . . . . . . . add 56
x = -9/6 = -3/2 . . . . divide by 6 and simplify
The solution of the equation is x = -3/2.

<em>Check</em>
Substituting -3/2 for x in the original equation, we get ...
4[-3/2 +2(3(-3/2) -7)] = 22(-3/2) -65
4[-3/2 +2(-23/2)] = -33 -65
4[-3/2 -23] = -98
4[-49/2] = -98 . . . . . . . true
