The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$x = \frac{27}{10}$$
We get the answer: x = 27/10
-(26/5)+x = -(5/2)
Expand brackets in the left part
-26/5+x = -(5/2)
Expand brackets in the right part
-26/5+x = -5/2
Move free summands (without x)
from left part to right part, we given:
$$x = \frac{27}{10}$$
We get the answer: x = 27/10
