A Bouquet of lillies and tulips has 12 flowers. Lillies cost $3 each, and tulips cost $2 each. The bouquet costs $32. Write and solve a system of linear equations to find the number of lillies and tulips in the bouquet.

Let l be the number of lillies and t be the number of tulips. We're given 2 equations:

l + t = 12

3l + 2t = 32

With this system of equations, we can solve it 3 ways.
