Answer:

  • Miguel: 29 points
  • Alonzo: 25 points

Explanation:

Let 'a' and 'm' represent the respective scores of Alonzo and Miguel. The given relations are ...

a + m = 54

m - a = 4

Adding 'a' to the second equation gives an expression for m that we can substitute into the first equation:

m = a +4

a +(a +4) = 54 . . . . . substitute for m

2a = 50 . . . . . . . . subtract 4

a = 25 . . . . . . . divide by 2

m = 25 +4 . . . Miguel's score

Alonzo scored 25; Miguel scored 29 points.
