    14*(-1)    
8 + ------- = y
       7       
$$\frac{\left(-1\right) 14}{7} + 8 = y$$
Detail solution
Given the linear equation:
8-1/7*14 = y

Looking for similar summands in the left part:
6 = y

Move free summands (without y)
from left part to right part, we given:
$$0 = y - 6$$
Move the summands with the unknown y
from the right part to the left part:
$$- y = -6$$
Divide both parts of the equation by -1
y = -6 / (-1)

We get the answer: y = 6
