The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{x}{2} - \frac{1}{2}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-1\right) x}{2} = - \frac{1}{2}$$
Divide both parts of the equation by -1/2
We get the answer: x = 1
0 = (1/2)*(x+(-1))
Expand brackets in the right part
0 = 1/2x-1)
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{x}{2} - \frac{1}{2}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-1\right) x}{2} = - \frac{1}{2}$$
Divide both parts of the equation by -1/2
x = -1/2 / (-1/2)
We get the answer: x = 1
