The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move the summands with the unknown x
from the right part to the left part:
$$- \frac{7 x}{15} = \frac{1}{3}$$
Divide both parts of the equation by -7/15
We get the answer: x = -5/7
x/5 = (2*x+1)/3
Expand brackets in the right part
x/5 = 2*x/3+1/3
Move the summands with the unknown x
from the right part to the left part:
$$- \frac{7 x}{15} = \frac{1}{3}$$
Divide both parts of the equation by -7/15
x = 1/3 / (-7/15)
We get the answer: x = -5/7
