solve what?

You still haven't solved these XD... At least attempt them on your own. If you at least try and come up with an answer, I will explain how to do them. If you don't try, you will never learn :S.
i agree. just a hint. try to get rid of radicals by squaring both sides of the equation
i have done so you never responded to my answers
It never told me you responded, my bad, can you post your old attempts/questions?
where did my other post go?
i think the last one would be 0
Nope. Plug 0 in for m, and you get -1=0 this isn't true. To solve the last one.... \[4\sqrt(m-1)-\sqrt(15m)-1=0\]\[16(m-1)-15m-1=0\]\[m-2=0\]\[m=2\] Hopefully the steps are self explanatory. Square both sides, simplify.
i found my first answer i came up with 15
Nope :S. Plugging in 15 gives sqrt(202)=20. This isn't true. To solve the first one.. \[\sqrt(9x+67)=5+x\]\[9x+67=x^2+10x+25\]\[x^2+x-42=0\] Quadratic equation to get your answer, plug into original equation to verify that both solutions work.
no m=15 not that problem
