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