hopefully I have read this right
:
sqrt%28y%2B1%29-5=8
sqrt%28y%2B1%29=13
:
y+1=169.....squared both sides
:
y=168

sqrt%28y%2B1%29-5=8 Start with the given equation.


sqrt%28y%2B1%29=8%2B5 Add 5 to both sides.


+sqrt%28y%2B1%29+=13 Combine like terms.


y%2B1=13%5E2 Square both sides


y%2B1=169 Square 13 to get 169


y=169-1 Subtract 1 from both sides.


y=168 Combine like terms.



=====================================================

Answer:

So the solution is y=168
