The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = -8$$
Divide both parts of the equation by -20
We get the answer: x = 2/5
6-5*(4*x-1) = 3
Expand brackets in the left part
6-5*4*x+5*1 = 3
Looking for similar summands in the left part:
11 - 20*x = 3
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = -8$$
Divide both parts of the equation by -20
x = -8 / (-20)
We get the answer: x = 2/5
