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