The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{5} = x - \frac{3}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-6\right) x}{5} = - \frac{3}{5}$$
Divide both parts of the equation by -6/5
We get the answer: x = 1/2
(3-x)/5 = x
Expand brackets in the left part
3/5-x/5 = x
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{5} = x - \frac{3}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-6\right) x}{5} = - \frac{3}{5}$$
Divide both parts of the equation by -6/5
x = -3/5 / (-6/5)
We get the answer: x = 1/2
