The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 6$$
Divide both parts of the equation by -5
We get the answer: x = -6/5
-5*x-6 = 0
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 6$$
Divide both parts of the equation by -5
x = 6 / (-5)
We get the answer: x = -6/5
