Answer 1

9514 1404 393

Answer:

52 measures

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.
