word problem equation
Ben and Vince are playing a card game involving green and yellow cards. They get 3 points every time they draw a green card, and 5 points for yellow. The winner is the first to get to 50 points.
Ben has 41 points and nine cards. How many cards does he have of each color?
Let G be the number of green cards and Y be the number of Yellow cards

7=Y so G=2
So Ben has 7 yellow cards and 2 Green cards.
I hope this helps.
