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:
We get the answer: x = 5
-(x+5)+2*x = 0
Expand brackets in the left part
-x-5+2*x = 0
Looking for similar summands in the left part:
-5 + x = 0
Move free summands (without x)
from left part to right part, we given:
We get the answer: x = 5
