Algebra

[DragonMasterX]

My calculator could never do such things unfortunately, but now that I look back I'm glad it never did allow me to, or I'd be unable to do such a simplicity compared to the stuff they teach at Math I at college. Then again, I never did need them, I learned Substitution and Elimination really fast. And since we're on the topic, I gotta hand it to you Crim, I wouldn't have been able to explain the two methods with so much patience!
