The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without m)
from left part to right part, we given:
$$- 4 m = 24$$
Divide both parts of the equation by -4
We get the answer: m = -6
-4*(6+m) = 0
Expand brackets in the left part
-4*6-4*m = 0
Move free summands (without m)
from left part to right part, we given:
$$- 4 m = 24$$
Divide both parts of the equation by -4
m = 24 / (-4)
We get the answer: m = -6
