Solving rational equations with unlike denominators

[FAQ]

Ok, so before every says that I am just looking for answers, I would like to say my teacher has been on "stress leave" for the past 5 weeks and we have been tought by a very bad "math" teacher

Im having a hard time with Rational Equations, I guess because I have no notes on it So I am looking for some help. I was given a sheet and have to have it done but since I can only do a few, I am asking for your help...

Question #1
7/s-1 - 10/s^2-s = s+2/s I don't even know where to start

Question #2
2y/y^2+3y-10 + 4/y^2+6y+5 = 3y/y^2-y-2

Start off by getting rid of the annoying denominators. Multiply through the equations by the highest powered denominator you can find and it'll turn into a much friendlier equation.

Just remember that none of the denominators can equal zero, so you must check your solutions with the original equation!
