The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$2 x = -5$$
Divide both parts of the equation by 2
We get the answer: x = -5/2
5+2*x = 0
Move free summands (without x)
from left part to right part, we given:
$$2 x = -5$$
Divide both parts of the equation by 2
x = -5 / (2)
We get the answer: x = -5/2
