Homework Help: pre-calculus

Posted by natalie on Tuesday, September 20, 2011 at 4:27pm.

Could someone please help me with this problem?
square root of (2x+1) -5 = 8
I think I take the 5 and add it to the 8 and then I have
square root of (2x+1) = 13
then do I square both sides and end up with 2x+1 = 13^2
2x+1=169
2x+1-1=169-1
2x=168
x=84 am I even close on this?
