The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- x = x - 12$$
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
12-x = x
Move free summands (without x)
from left part to right part, we given:
$$- x = x - 12$$
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
