The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$10 x = -5$$
Divide both parts of the equation by 10
We get the answer: x = -1/2
10*x+5 = 0
Move free summands (without x)
from left part to right part, we given:
$$10 x = -5$$
Divide both parts of the equation by 10
x = -5 / (10)
We get the answer: x = -1/2
