The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = 3 x - \frac{9}{10}$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = - \frac{9}{10}$$
Divide both parts of the equation by -2
We get the answer: x = 9/20
x+3/6 = 3*x-2/5
Move free summands (without x)
from left part to right part, we given:
$$x = 3 x - \frac{9}{10}$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = - \frac{9}{10}$$
Divide both parts of the equation by -2
x = -9/10 / (-2)
We get the answer: x = 9/20
