The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = -1$$
Divide both parts of the equation by -8
We get the answer: x = 1/8
-8*x+4 = 3
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = -1$$
Divide both parts of the equation by -8
x = -1 / (-8)
We get the answer: x = 1/8
