The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$\frac{x}{4} = x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-3\right) x}{4} = -12$$
Divide both parts of the equation by -3/4
We get the answer: x = 16
x/4+13 = x+1
Move free summands (without x)
from left part to right part, we given:
$$\frac{x}{4} = x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-3\right) x}{4} = -12$$
Divide both parts of the equation by -3/4
x = -12 / (-3/4)
We get the answer: x = 16
