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:
$$4 x = 115$$
Divide both parts of the equation by 4
We get the answer: x = 115/4
(2*x-5)+2*x = 110
Expand brackets in the left part
2*x-5+2*x = 110
Looking for similar summands in the left part:
-5 + 4*x = 110
Move free summands (without x)
from left part to right part, we given:
$$4 x = 115$$
Divide both parts of the equation by 4
x = 115 / (4)
We get the answer: x = 115/4
