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:
$$- 5 x = 15$$
Divide both parts of the equation by -5
We get the answer: x = -3
(3*x-10)-(8*x-5) = 10
Expand brackets in the left part
3*x-10-8*x+5 = 10
Looking for similar summands in the left part:
-5 - 5*x = 10
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
