Gamestop sells used gaming systems and games. You can buy an Xbox One for $150 and games for $25 each. Or, you can buy a Playstation 4 for $180 and games for $20 each. How many games would you need to purchase for your cost to be equal?

Choose which option has the correct equation for this situation AND the correct solution.

• 150x + 25 = 180 + 20x ; 2 games

• 150 + 25x = 180 + 20x ; 6 games

• 180 + 150 = 25x - 20x ; 66 games

• 150 - 25x = 180 - 20x ; -6 games

Solve for x 

• x = 16
• x = 28
• x = 1/26
• x = 26
