Answer:
-4
Step-by-step explanation:
18x - 9(x - 1) = 5(3x + 3)
Step 1: Distribute
18x - 9x - 9 = 15x + 15
Step 2: Combine like terms
9x - 9 = 15x + 15
Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side
9x - 9 = 15x + 15
-9x -9x
-9 = 6x + 15
-15 -15
-24 = 6x
/6 /6
-4 = x
