X = 2, Y = 8

X = 3, Y = 7

X = 4, Y = 6

X = 5, Y = 5

The number of songs in the playlist on her phone = 10

The number of authors of the songs on her playlist = 2

X + Y = 10

Where X represent the number of Beyonce's song on her playlist and Y represent the number of Jennifer Lopez's song on her playlist

X + Y = 5 + 5 = 10

Which gives 5 Beyonce's and 5 Jennifer Lopez's songs
