The solution

You have entered [src]
20 - 7*(5*x - 4) = 6
$$20 - 7 \left(5 x - 4\right) = 6$$
Detail solution
Given the linear equation:
20-7*(5*x-4) = 6

Expand brackets in the left part
20-7*5*x+7*4 = 6

Looking for similar summands in the left part:
48 - 35*x = 6

Move free summands (without x)
from left part to right part, we given:
$$- 35 x = -42$$
Divide both parts of the equation by -35
x = -42 / (-35)

We get the answer: x = 6/5
