Three girls downloaded a total of 36 songs on their iPods. Jane downloaded twice as many as Inez and since Tracy wanted to have the most, she downloaded one more than Jane did. How many songs did each girl download?

Inez = x
Jane = 2x
Tracy = 2x + 1

All together, the equation is : x+2x+(2x+1)=36
First, combine like terms. 5x + 1 = 36
Subtract 1 on both sides. 5x = 35
Divide each side by 5. x = 7

Now, plug 7 into each girl's expression. 

Inez: 7
Jane: 2(7) = 14
Tracy: 2(7) + 1 = 15

Hope this helps :)
