solving equations simultaneously
solving equations simultaneously
(OP)
I cant seem to get this to work, any suggestions?
a:0
b:0
c:0
Given
76-60-b*3000-a*2000=0 (bouleian =)
80-c*4000-60-b*3000=0 (bouleian =)
c=a+b (bouleian =)
Find(a,b,c)=
then i get an error in the find that says the variable or function is not defined above...help
a:0
b:0
c:0

RE: solving equations simultaneously
try varying your initial guesses
try using minerr
The error message confuses me, I think the cause may be a typo somewhere rather than the above.

I've tried the system as above (mathcad V13) and got same message "Function not defined" or "This variable is undefined".
Any help?
I can e-mail my system of equations to whoever is interested in giving me a hand.
Thanks
