Ali, Veli, and Selami played connect four with each other. Ali won 5 games and lost 3 games. Veli won 1 game and lost 4 games. If Selami lost 4 games, how many did she win?
I created a graph (hopefully gives you a headstart) and maybe try trial-and-error
Ali | Veli | Salami |
Wins-5 | 1 | 4 |
Losses-3 | 4 |
If Ali won 5 games, that means Veli and Selami lost 5 games combined. We know Veli lost 4 games so Selami lost 1 game. If Ali lost 3 games then Veli and Ali won 3 games in total. Veli won 1 game so Selami won 2 games.
