Step-by-step explanation:
18x - (8x-7) = 67
Step 1: Simplify both sides of the equation.
18x - (8x-7) = 67
18x+-1 (8x-7) = 67 (Distribute the Negative Sign)
18x+-1 (8x) + (-1) (-7) = 67
18x+-8x+7=67
(18x+-8x) + (7) = 67 (Combine Like Terms)
10x+7=67
10x+7=67
Step 2: Subtract 7 from both sides.
10x+7-7=67-7
10x=60
Step 3: Divide both sides by 10.
