Answer:
x = 1
Step-by-step explanation:
Subtract the right side of the equation and simplify:
9x -4 -6x -2(x +1) +5 = 0
9x -6x -2x -4 -2 +5 = 0 . . . . . eliminate parentheses
x -1 = 0 . . . . . . . . . . . . . . . . . . collect terms
x = 1 . . . . . . . . . . . . . . . . . . . . . add the opposite of the constant
