The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = 2 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 2$$
Divide both parts of the equation by 4
We get the answer: x = 1/2
x-2 = -3*x
Move free summands (without x)
from left part to right part, we given:
$$x = 2 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 2$$
Divide both parts of the equation by 4
x = 2 / (4)
We get the answer: x = 1/2
