you usually solve equations of this kind:

,

by squaring the both sides and assuming that (we are talking for REAL solutions):

and

Now, consider the first equation:

, which is >0. So for x we get:

Thanks for the help but I used the wrong number after the = sign it should read

(Sqrt)of (3/2X-5) -10=-8 so I get

(sqrt) of (3/2x-5)=2 so then I get

3/2x-5=4 then

3/2x=9 then

3x=18

x=6

Thanks a bunch for the help! K
