9(x -  4) - 8 = 5x

First, distribute so that you can expand it easier.
(9)(x) + (9)(-4) - 8 = 5x
Second, the first two parentheses combine to make '9x'.
9x + (9)(-4) - 8 =5x
Third, multiply 9 × 4 to get 36.
9x - 36 - 8 = 5x
Fourth, add '36 - 8' to get 44.
9x - 44 = 5x
Fifth, subtract '9x' from both sides.
-44 = 5x - 9x
Sixth, subtract '5x - 9x' to get '-4x'.
-44 = -4x
Seventh, divide both sides by '-4'.
\frac{-44}{-4} =x
Eighth, change the fraction into a negative.
\frac{44}{4} =x
Ninth, 44 ÷ 4 = 11, so simplify your fraction to 11 and switch sides.
x = 11

Answer: x = 11

9x-44=5x
Subtract 5x
9x-44-5x=0
4x-44=0
Add 44
4x=44
Divide by 4
x= \frac{44}{4}
x=11
The answer is:  x=11
