Howard downloaded 6 more songs than erin . lee downloaded 3 more than howard. lee downloaded 16 songs. how many songs did erin downloaded?

• Howard: x+6
(Erin will be x for now since we don’t know how many songs she has downloaded)

• Lee: (x+6)+3 = 16
x+9 = 16
x = 7
(You don’t really need the bracket but it’s easier to see with it in. So, since Howard is x+6, Lee has downloaded 3 more than him so we’ll add 3. Simplify it so we get x+9. The equation equals 16 because that is how many Lee has downloaded all together. To get x on its own we take 9 from 16 which gives us 7 as our answer.)

I hope this helped I tried my best to explain. If you have any questions feel free to ask.
