hero · Answer

x + y = 27000
.04x + .09y = 1930

hero · Answer

Do you have any clue what to do from here?

anonymous · Answer

Well I would want to maybe use substitution to solve for one?

hero · Answer

yup, but...I recommend solving both equations for y first

anonymous · Answer

So, like, x+y=27000:
Does y=27000-x?

hero · Answer

Yes, like that. Now do it for the other equation

anonymous · Answer

Does x=10,000?

anonymous · Answer

Not sure
I came up with 10,000,17000

anonymous · Answer

Oh...wait, HA!  That works!  TY!
