An artist bought a set of 10 paintbrushes that contained x small paintbrushes and y large paintbrushes. The number of small paintbrushes in the set was 4 times the number of large paintbrushes in the set. Which system of equations can be used to find the numbers of small paintbrushes and large paintbrushes in the set?

• x + y = 10, x = 4y

• x – y = 10, x = 4y

• x + y = 10, y = 4x

• x – y = 10, y = 4x
