The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 24$$
Divide both parts of the equation by -4
We get the answer: x = -6
(4*x-13)-(8*x-2) = 13
Expand brackets in the left part
4*x-13-8*x+2 = 13
Looking for similar summands in the left part:
-11 - 4*x = 13
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 24$$
Divide both parts of the equation by -4
x = 24 / (-4)
We get the answer: x = -6
