x = number of small pumpkins at $2 each
y = number of large pumpkins at $8 each
x + y = 320
2x + 8y = 1900
From the top equation, get
y = 320 - x,
plug this into the bottom equation, and solve for x. Then plug the solution for x into either equation and solve for y.
2x + 8(320 - x) = 1900
x = 110
y = 320 - x = 320 - 110
y = 210
