The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$\frac{x}{4} = \frac{x}{6} - 46$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{x}{12} = -46$$
Divide both parts of the equation by 1/12
We get the answer: x = -552
1/4*x+27 = 1/6*x-19
Move free summands (without x)
from left part to right part, we given:
$$\frac{x}{4} = \frac{x}{6} - 46$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{x}{12} = -46$$
Divide both parts of the equation by 1/12
x = -46 / (1/12)
We get the answer: x = -552
