The solution
Detail solution
Given the linear equation:
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 = 8
-x+2*x-8 = 0
Looking for similar summands in the left part:
-8 + x = 0
Move free summands (without x)
from left part to right part, we given:
We get the answer: x = 8
