The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$5 x = -20$$
Divide both parts of the equation by 5
We get the answer: x = -4
5*x+8 = -12
Move free summands (without x)
from left part to right part, we given:
$$5 x = -20$$
Divide both parts of the equation by 5
x = -20 / (5)
We get the answer: x = -4
