Question 24017
1. {{{3sqrt(x) = 5}}}
{{{sqrt(x) = 5/3}}}
x = 25/9


2. {{{sqrt(13y-3) =  sqrt(7y+9)}}}
{{{13y-3 = 7y+9}}}
{{{6y-3 = 9}}}
{{{6y = 12}}}
--> y = 12/6
--> y = 2


3. {{{sqrt(x-5) - 1 = sqrt(x)}}}

now this one is far more tricky and i would hesitate to say that my version of what you have written is wrong, so can you please re-submit the correct/clearer version of part3.
