x = pencils 
y = pens 

x + 1.5y = 7  [Stefan spent $7 at the store]
x + y = 6       [He bought a total of 6 items]

The system of equation that can be used to find the number of pencils and pens is

x + y = 6

x + 1.50y = 7

How to represent system of equation?

The pencil at the stationery store costs $1, and the pen costs $1.50.

This means each pencil cost $1 and each pen cost $1.50.

He spent a total of $7.
