Answer:
X = 6
Step-by-step explanation:
6-6X = 7X -9X -18 Combine 7x -9x
6 - 6x = -2x -18 Add 6x to both sides of the equation
6 = 4x - 18 Add 18 to both sides of the equation
24 = 4x Divide both sides by 4
6 = x
Check:
6-6X = 7X -9X -18
6 - 6(6) = 7(6) -9(6) -18
6 - 36 = 42 - 54 -18
-30 = 1-12-18
-30 =-30
