Gamestop charges only $7 per used video game. Gamefly charges a one time fee of $16 plus an additional $3 per used video game. Write and solve an equation to find when the cost of buying used video games from both companies below will be the same.

The cost of buying used video games from both companies will the same at the 4th video game.

Step-by-step explanation:

Gamestop equation: 7x

Gamefly equation: 3x + 16

7x = 3x + 16

Subtract 3x from both sides;

4x = 16

Divide both sides by 4x

x = 4
