The solution
You have entered
[src]
7 - 10*x + -8 + 8*x + 10*x + 6 = -8
$$\left(10 x + 6\right) + \left(\left(7 - 10 x\right) + \left(8 x - 8\right)\right) = -8$$
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:
$$8 x = -13$$
Divide both parts of the equation by 8
We get the answer: x = -13/8
(7-10*x)-(8-8*x)+(10*x+6) = -8
Expand brackets in the left part
7-10*x-8+8*x+10*x+6 = -8
Looking for similar summands in the left part:
5 + 8*x = -8
Move free summands (without x)
from left part to right part, we given:
$$8 x = -13$$
Divide both parts of the equation by 8
x = -13 / (8)
We get the answer: x = -13/8
