rational expressions: solve 8/x+4-3/3x+12, etc

[tseday871221]

I HAVE THE EQUATION 8/X+4 - 3/3X+12

i KNOW THAT i HAVE TO MAKE THE EQN HAVE LIKE DEMOMINATORS

BUT AFTER I FIGURE IT OUT..I FORGET WHAT TO DO NEXT.


AND THE SAME GOES FOR THIS EQN:

7
__________ - 5X

X^2

WHAT IS IT THAT THEY WANT ME TO DO WITH THIS EQN?

Neither of the things you have posted are EQUATIONS...an equation has an equals sign between two things.

So, I'd hate to try to guess what you mean.

Could you repost with the EXACT TEXT of the problem you're trying to solve?
