minette gave mark and michelle as much money as each had. and michelle gave much as each had then michelle gave mark and minette as much as each had.then each of them has 24.00
how much money did they have at the beginning?
In the beginning: Minette had T, Mark had K, and Michelle had L.
After step 1: Minette had (T-K-L), Mark had 2K and Michelle had 2L.
After step 2: Minette had (2T-2K-2L), Mark had 4K and Michelle had (3L-T-K).
Solve 3 simultaneous equations of 3 variables:
2T - 2K - 2L = 24.00
4K = 24.00
-T - K + 3L = 24.00
