During a sale at the local department store, you buy three sweatshirts and two pairs of sweatpants for $85.50. Later you buy three more sweatshirts and four more pairs of sweatpants for $123.00 What is the sale price of each sweatshirt and each pair of sweatpants?

let x = shirts and y = pants

3x + 4y = 123

3x + 2y = 85.5

Subtract second equation from first.

2y = 37.5

Can you carry on from there?
