The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$12 x = 4 x + 16$$
Move the summands with the unknown x
from the right part to the left part:
$$8 x = 16$$
Divide both parts of the equation by 8
We get the answer: x = 2
12*x-20 = 4*x-4
Move free summands (without x)
from left part to right part, we given:
$$12 x = 4 x + 16$$
Move the summands with the unknown x
from the right part to the left part:
$$8 x = 16$$
Divide both parts of the equation by 8
x = 16 / (8)
We get the answer: x = 2
