Answer: The solution is x = 1/5
Steps:
Distribute the terms inside the parentheses
18x + 12 + 5 = 5x +20 - 2x
Combine like terms on both sides of the equation
18x + 17 = 3x + 20
Subtract 3x from both sides of the equation
18x−3x+17=3x−3x+20
15x+17=20
Subtract 17 from both sides of the equation
15x+17−17=20−17
15x=3
Divide both sides by 15
15x/15 = 3/15
x = 1/5
