Question 1035556
.
Hello! I've tried solving this problem multiple times but I'm not sure if I've gotten the right answer or if I was doing it right. 

Solve: {{{(7x+1)/(x^2-8x+15)+3x/(x-5)=-1/(x-3)}}}

This is my work: 


<pre>
First off, I marked that x cannot equal 5 or 3, because of how(x-3) and (x-5) are in the denominator and 
I can't have 0 in the denominator. 

I turned it into {{{(7x+1)/(x-5)(x-3)+3x/(x-5)=-1(x-3)}}}    ( <<<--- actually, right side is {{{-1/(x-3)}}}, but I consider your error as a typo here )

I noticed that after I factored out {{{x^2-8x+15}}} I could rationalize the denominator to (x-5)(x-3) by multiplying 3x/(x-5) 

with (x-3) and -1/(x-3) with (x-5) and cancel it all out to just end up with {{{(7x+1)+3x(x-3)=-1(x-5)}}}.           <<<--- CORRECT!

Next, I simplified it down to {{{7x+1+3x^2-9x=-x+5}}} to {{{3x^2-x-4=0}}}.                      <<<--- CORRECT!

I didn't know if I could factor it out anymore mentally, so I chose my safest bet which was using 
the quadratic formula to get x=4/3 and x=-1.                                                                     <<<--- CORRECT!

Those two answers would work because it's not 5 or 3 (because then it would equal 0).                            <<<--- CORRECT!

Am I right? Or did I do something wrong? I hope I was clear enough and I would really appreciate the help!    <<<---  You are right. No error. At least, I do not see it.
