I can't seem to get past this problem...
2x + 5
3x x-8
For the answer I keep getting something like: 17x-13
3x(x-8)
Thanks for your help!

Once you find the LCD, which you have done correctly, you have to multiply the numerator and denominator of each by the same factor:
2x (x-8) + 5 (3x)
3x (x-8) x-8 (3x)
2x^{2} - 16x + 8x = 2x^{2} -8x = (x)(2x -4) = 2x-4
(3x)(x-8) 3x^{2} - 24x (x)(3x-24) 3x-24
your answer = {2x(x-8) + 15x}/3x(x-8)
= (2x^{2}-16x+15x)/3x(x-8)
= (2x^{2}-x)/3x(x-8)
=x(2x-1)/3x(x-8)
=2x-1/(3(x-8))

The end answer is not right on this. Sorry multiplication error. Should be 2x-1/3x-24
