-2=0

8^x =16^x+2, 2 x 8 = 16

log sub 5 (2x+3)=2

2(7/2)+3=2

log sub 5 (2x+3)=2

log sub 5 =11

The first and second lines make no sense whatsoever.

The last is even more confusing.

Watch

8^x = 16^(x+2)

8^x = 8^2(x+2)

x= 2x+4 solve for x.

On the next

log5 (2x+3)=2

2x+3=25

solve for x.

I think you need a tutor to help you study this: your work seems helter skelter and in need of organized thought. Discuss this with your mom quickly.
