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
(25+x)+10 = 40
Expand brackets in the left part
25+x+10 = 40
Looking for similar summands in the left part:
35 + x = 40
Move free summands (without x)
from left part to right part, we given:
$$x = 5$$
We get the answer: x = 5
