i can come up with the general formula for the DE but since there are complex eigenvalues and eigenvectors i get lost when converting it to sine and cosine, just wandering if there is a simpler way to this without expanding out the whole equation and then simplifying.

an example is:

x' = 3x -5y
y' = 4x -5y

(x) (4-x^2)^2 OR
"x times the square root of 4 minus x squared", where b=2 and a=0.

If i wish to place 2 bets......of which only one can win.....

1 at a probable payout of $2.25, and the other at a probable payout of $2.95

How much do I have to bet on each of these so that the one winner (which will eliminate the other) will give me a profit of $100.00 AFTER covering the cost of both bets?

What is the formula for figuring this out?

What type betting calculator can compute this?

Thank you.
