4(x - 5) + 5 = 3x - 6 - x

4x - 4(5) + 5 = 3x - 6 - x

4x - 20 + 5 = 3x - x - 6

4x - 15 = 2x - 6           (add 15 to each side)

4x - 15 + 15 = 2x - 6 + 15

4x = 2x + 9              (subtract 2x from each side)

4x - 2x = 2x - 2x + 9

2x = 9                    (divide 2 from each side)

2x/2 = 9/2

[tex]x= \frac{9}{2}=4 \frac{1}{2} =4.5\ \textless \ -answer[/tex]
