Kelly has four times as many songs on her music player as Lou Tiffany has six times as many songs under player as Loop altogether they have 682 songs on their music players how many songs does Kelly have

Let x = number of songs on Lou's player

Let k = number of songs on Kelly's player

Let t = number of songs on Tiffany's player

x+k+t=682

k=4x

t=6x

Now use substitution

x + (4x) + (6x) = 682

11x=682

Divide both sides by 11 and get x=62

To find how many songs Kelly has, substitute 62 for x in k=4x to get k=248

Kelly has 248 songs on her music player
