$8=3+|10y+5|$

by subtracting $3$ ,

$Rightarrow 5=|10y+5|$

by removing the absolute value sign,

$Rightarrow{(10y+5=5),(10y+5=-5):}$

(Note: Since the absolute value erases the negative sign, we need to consider both positive and negative values.)

by subtracting $5$ ,

$Rightarrow{(10y=0),(10y=-10):}$

by dividing by $10$ ,

$Rightarrow{(y=0),(y=-1):}$

Hence, $y=-1,0$ .

I hope that this was helpful.
