The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 2
We get the answer: x = -1/2
2*x+1 = 0
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 2
