Ivy and Cammie sold tulip and daffodil bulb packages for their spring fundraiser. Ivy sold 12 packages of tulip bulbs (x) and 14 packages of daffodil bulbs (y) for a total of $180.00. Cammie sold 9 packages of tulip bulbs and 16 packages of daffodil bulbs for a total of $168. Write a system of linear equations can be used to find the price per package for each of the two kinds of bulbs?

12x + 14y = 180
9x + 16y = 168
