The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$x = 130$$
We get the answer: x = 130
x+125 = 230+25
Looking for similar summands in the right part:
125 + x = 255
Move free summands (without x)
from left part to right part, we given:
$$x = 130$$
We get the answer: x = 130
