Answer:
5x -15 + 4x + 12 = 3x -3
5x + 4x - 3x = 15 - 12 - 3 (put all like terms in one side)
6x = 0
x = 0/6
x= 0
x=0
Explanation:
Solve for x.
5(x - 3) + 4(x + 3) = 3(x - 1)
Distribute
5x -15 +4x +12 = 3x-3
Combine like terms
9x -3 = 3x-3
Add 3 on each side
9x -3+3 = 3x-3
9x = 3x
Subtract 3x from each side
9x-3x = 3x-3x
6x =0
Divide by 6
6x/6 = 0/6
