/ 31\ 2*|y + --| = -4/3 \ 10/
$$2 \left(y + \frac{31}{10}\right) = - \frac{4}{3}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without y)
from left part to right part, we given:
$$2 y = - \frac{113}{15}$$
Divide both parts of the equation by 2
We get the answer: y = -113/30
2*(y+(31/10)) = -4/3
Expand brackets in the left part
2*y+2*31/10) = -4/3
Move free summands (without y)
from left part to right part, we given:
$$2 y = - \frac{113}{15}$$
Divide both parts of the equation by 2
y = -113/15 / (2)
We get the answer: y = -113/30
