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

by subtracting 33,

Rightarrow 5=|10y+5|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.
