5y-6=8y+6 

First, let's add six to each side: 
 5y-6=8y+6 
    +6      +6
this gives
 5y=8y+6+6 
simplified to 
5y=8y+12
subtract 8y both sides
5y=8y+12
-8y    -8y
5y-8y=12
-3y=12
divide both sides by -3
$$\frac{-3y}{-3}=\frac{12}{-3}$$
$$y=\frac{12}{-3} = -4$$

Here you go, hope this helps some  :)
