Answer:

2[tex]\frac{4}{15}[/tex]

Step-by-step explanation:

First factor our the (4-x):  (8*4)(8*x)
Then we have 36 - 8x = 7x + 2

Isolate the x:

32 -2 = 8x + 7x

Simplify both sides:

30 = 15x

Divide both sides by 15

[tex]\frac{30}{15}[/tex] = [tex]\frac{15x}{15}[/tex]

Simplify further if necessary:

x = 2
