The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$x = 10$$
We get the answer: x = 10
90+x-4*10 = 60
Looking for similar summands in the left part:
50 + x = 60
Move free summands (without x)
from left part to right part, we given:
$$x = 10$$
We get the answer: x = 10
