At Gamestop you can buy an XBox One for $150 and each game to go with it would cost $24. Or you can buy a Playstation 4 for $180 and each game cost $20. Write an equation to determine how many games would need to be purchased for the cost to be the same?

• 150x + 24 = 180 + 20x

• 150 + 24x = 180 + 20x

• 180 - 150 = 24x + 20x

• 150 - 24x = 180 - 20x
