Question

At an office supply store, Samantha bought 5 notebooks and 2 pens for $9. Jeffrey bought 3 notebooks and 2 pens for $6. Find the price of a notebook and the price of a pen.
(please help I'm stuck)

Answer 1

5 n + 2 p = 9

3 n + 2 p = 6

subtract the equations to eliminate p ... 2 n = 3
... solve for n, then substitute back to find p
