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'.

(-44)/(-4) =x
Eighth, change the fraction into a negative.

(44)/(4) =x
Ninth, 44 ÷ 4 = 11, so simplify your fraction to 11 and switch sides.

x = 11

Answer: x = 11

9(x-4)-8=5x
Distributhing 9 through parentheses

9x-9*4-8=5x

9x-36-8=5x

9x-44=5x
Subtract 5x

9x-44-5x=0

4x-44=0
Add 44

4x=44
Divide by 4

x= (44)/(4)

x=11
The answer is:
x=11
