Answer:
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
