Ricardo has 2 cases with x number of games in each. This means 2x is the amount of video games in both. He gives away 4. He now has 2x-4 and has 10 left. This is 2x-4=10. Solve for x.
2x - 4 = 10
2x = 14
there were 7 games in each case
14 divided by 2 cases = 7
7 games were in each case
The total number of video games he had to begin with is 4+10=14.
Divide the total games by 2 (cases) and you get 7 games in each case
Both the cases contained equivalent no. of video games so after he gave 4 games and was left with 10 afterwards so we can conclude that he had 14 games in total in the first place and if we divide it by 2 for the purpose of distributing the games evenly in both the cases we are left over with 7
