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:
$$22 x = 60$$
Divide both parts of the equation by 22
We get the answer: x = 30/11
23*x-60-x = 0
Looking for similar summands in the left part:
-60 + 22*x = 0
Move free summands (without x)
from left part to right part, we given:
$$22 x = 60$$
Divide both parts of the equation by 22
x = 60 / (22)
We get the answer: x = 30/11
