The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- 24 x = -6$$
Divide both parts of the equation by -24
We get the answer: x = 1/4
6*(1-4*x) = 0
Expand brackets in the left part
6*1-6*4*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 24 x = -6$$
Divide both parts of the equation by -24
x = -6 / (-24)
We get the answer: x = 1/4
