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:
$$x = 36$$
We get the answer: x = 36
3*(x-6)-2*x = 18
Expand brackets in the left part
3*x-3*6-2*x = 18
Looking for similar summands in the left part:
-18 + x = 18
Move free summands (without x)
from left part to right part, we given:
$$x = 36$$
We get the answer: x = 36
