How much does each pumpkin weigh?

how much does each squash weigh?

Answer 1

3p + 2s = 27.5

4p + 3s = 37.5

Multiplies first equation by 4 and second equation by -3

12p + 8s = 110

-12p + -9s = -112.5

Adding them together

-s = -2.5

s = 2.5

3p + 2(2.5) = 27.5

3p +5 = 27.5

3p = 22.5

p = 7.5

pumpkins weigh 7.5 pounds and squash weighs 2.5 pounds
