The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$5 x = x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -12$$
Divide both parts of the equation by 4
We get the answer: x = -3
5*x+4 = x-8
Move free summands (without x)
from left part to right part, we given:
$$5 x = x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -12$$
Divide both parts of the equation by 4
x = -12 / (4)
We get the answer: x = -3
