The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = -24$$
Divide both parts of the equation by -2
We get the answer: x = 12
-2*x-8 = -32
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = -24$$
Divide both parts of the equation by -2
x = -24 / (-2)
We get the answer: x = 12
