The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{2} = -2$$
Divide both parts of the equation by -1/2
We get the answer: x = 4
2^1-x/2 = 0
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{2} = -2$$
Divide both parts of the equation by -1/2
x = -2 / (-1/2)
We get the answer: x = 4
