Andre wants to purchase some onions and tomatoes to make spaghetti for a friend’s birthday dinner. He looks at two different recipes. Recipe A calls for 4 times the number of tomatoes, x, plus 5 times the number of onions, y, which should produce 109 plates of spaghetti. Recipe B calls for 2 times the number of tomatoes used minus the number of onions, which should produce 23 plates of spaghetti.
