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:
$$5 x = -1$$
Divide both parts of the equation by 5
We get the answer: x = -1/5
(5*x-1) = -2
Expand brackets in the left part
5*x-1 = -2
Move free summands (without x)
from left part to right part, we given:
$$5 x = -1$$
Divide both parts of the equation by 5
x = -1 / (5)
We get the answer: x = -1/5
