If you factorize all the terms of your two fractions (it's easy since they are all second degre) You will see the you can simplify afterwards quite a lot.
Should be looking like this:
5 should be the lowest common denominator. You can extract him out of both functions.
Start factorizing the term under the fraction of the right side. You will get (x+2)(x+3). Now multiplicate everything with that. All the fractions will disappear. Then you develop all the terms. And you will come back to an equation of the first degree. Answer should be -2/3.
For the last one, you have to put all the terms that arent on the fractions with (x-4) on these fractions. The you can switch to an multiplication by inversing one fraction. Finally you simplifie the second degrees and you look what's going to rest. Answer should be (x-2)/(2x-5).
