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:
$$x = 5$$
We get the answer: x = 5
1+x+(-2)*3 = 0
Expand brackets in the left part
1+x+-2*3 = 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:
$$x = 5$$
We get the answer: x = 5
