You can put this solution on YOUR website! (6/r)+(7/r-2)
-----
least common denominator: r(r-2):

Rewrite each fraction with a lcd as its denominator:
-----
(6(r-2))/lcd + (7r/lcd)
-------------------------------------
Combine the numerators over the lcd:
= (6r-12+7r)/lcd
-----------------------------------
= (13r-12)/(r(r-2))
