The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = 3 x - 1$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -1$$
Divide both parts of the equation by -2
We get the answer: x = 1/2
x+3/4 = 3*x-2/8
Move free summands (without x)
from left part to right part, we given:
$$x = 3 x - 1$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -1$$
Divide both parts of the equation by -2
x = -1 / (-2)
We get the answer: x = 1/2
