Miguel and Beth like to play video games together. Miguel has m video games, and Beth has b video games. Miguel has 4 more video games than Beth, and together they have a total of 24 video games. Which system of equations can be used to find how many video games belong to each friend?
Answer
A
the 2 by 1 column matrix row 1 m plus b is equal to 24 row 2 m is equal to b plus 4
B
the 2 by 1 column matrix row 1 m plus b plus 4 is equal to 24 row 2 b is equal to m plus 4
C
the 2 by 1 column matrix row 1 m plus b plus 4 is equal to 24 row 2 m is equal to b plus 4
D
the 2 by 1 column matrix row 1 m plus b is equal to 24 row 2 b is equal to m plus 4
Explanation
Together, Miguel and Beth have 24 games, so their total is m + b = 24. Miguel has 4 more games than Beth, which means m = b + 4. Choice A gives both equations, so it is the correct system.
