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:
$$12 x = 24$$
Divide both parts of the equation by 12
We get the answer: x = 2
9*x-4+3*x = 20
Looking for similar summands in the left part:
-4 + 12*x = 20
Move free summands (without x)
from left part to right part, we given:
$$12 x = 24$$
Divide both parts of the equation by 12
x = 24 / (12)
We get the answer: x = 2
