The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = -15$$
Divide both parts of the equation by -5
We get the answer: x = 3
-5*x+2 = -13
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = -15$$
Divide both parts of the equation by -5
x = -15 / (-5)
We get the answer: x = 3
