Answer 1

9514 1404 393

Answer:

  52 measures

Step-by-step explanation:

Let s represent the length of the second song. Then the first song's length is 108 -s, and the difference in length is ...

  (108 -s) -(s) = 4

  108 -2s = 4 . . . .collect terms

  54 -s = 2 . . . . divide by 2

  52 = s . . . . . add s-2

Grace's second song is 52 measures long.
