The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- \frac{3 x}{5} = 19$$
Divide both parts of the equation by -3/5
We get the answer: x = -95/3
8-3/5*x = 27
Move free summands (without x)
from left part to right part, we given:
$$- \frac{3 x}{5} = 19$$
Divide both parts of the equation by -3/5
x = 19 / (-3/5)
We get the answer: x = -95/3
