1. Answer:

   Joe bought 20 seed corn bags and 30 bags of dog food

   Step-by-step explanation:

   x + y = 50

   5x + 3y = 190

   Subtract y from both sides of the first equation

   x = 50 – y

   Put x into the second equation

   5(50 – y) + 3y = 190

   Distribute the 5

   250 – 5y + 3y = 190

   Combine like terms

   250 – 2y = 190

   Subtract 250 from both sides

   -2y = -60

   Divide both sides by -2

   y = 30

   Put y into the first equation

   x + 30 = 50

   Subtract 30 from both sides

   x = 20
