You can put this solution on YOUR website!
sqrt(2y) + 3 = 11
sqrt(2y)=8
Square both sides to get:
2y=64
y=32
Check the answer:
sqrt(2(32))+3=11
sqrt(64)+3+11
8+3=11
11=11

(sqrt of 2y) +3=11
first subtract both sides by 3 and we get ..
(sqrt of 2y) = 8
taking square of both sides we get
2y = 64
divide both sides by 2 and we get..
y = 32

Now if you want to verify you answer ,,,you can put the values of y in the given equation and if you get LHS = RHS,,,this means that you answer is correct..
hope this will help you
