The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = x + 12$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 12$$
Divide both parts of the equation by 2
We get the answer: x = 6
3*x-5 = x+7
Move free summands (without x)
from left part to right part, we given:
$$3 x = x + 12$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = 12$$
Divide both parts of the equation by 2
x = 12 / (2)
We get the answer: x = 6
