Answer:

Option D

Step-by-step explanation:

Given expression is,

10(2x - 4) + 5 = 2x - 8

By using distributive rule,

20x - 40 + 5 = 2x - 8

20x - 35 = 2x - 8

Now we subtract 2x from both the sides of the equation

20x - 35 - 2x = 2x - 8 - 2x

18x - 35 = -8

By adding 35 on both the sides of the equation

18x - 35 + 35 = - 8 + 35

18x = 27

By diving with 18 from both the sides of the equation

[tex]\frac{18x}{18}=\frac{27}{18}[/tex]

x = [tex]\frac{3}{2}[/tex]

Therefore, Option D will be the correct option.
