## simple question about finding A and B

80A = 12000 - AB
2000A = 2000 - AB

I can find A and B right? If not I can provide more??

Thanks :o !!

 Yes you can find out A and B !
 also is there any way to set up excel so that as i change the figures the answer what A and B is automatically changes? i'm sorry to be so bad at math - it's been like 12 years since i stuided any :o

honestly - i am using software that runs out in like 20 hours. this is a music hobby thing - i don't suppose you can give me the answer plus also if excell will do it for me?? i know it'd be simple for everyone here.... :) :) !!

there are online calculators but they don't seem to cope with the A*B component!!!
 Hey clemon. Minus the first equation from the second and collect the terms for the A's and solve for A. Then plug A into one of the equations and solve for B.
 they don't converge!! what about: 100=A/(100-B)+C 12000=A/(80-B)+C 200=A(5000-B)+C thanks!!
 Since both equations have an identical term (AB) solve both for that. http://www.wolframalpha.com/input/?i...+%3D+2000+-+AB
 thanks - i'm trying to find it with excel atm. not sure if these figures even converge tbh.
 Recognitions: Gold Member Science Advisor Staff Emeritus 80A = 12000 - AB 2000A = 2000 - AB Didn't you consider getting rid of the "AB" term by subtracting one equation from the other? 80A- 2000A= -1920A= 10000. Solve that for A and then solve either of the two equations, using that value of A, for B
