x=Sally´s strickers
8x=Tami´s strickers.

We can suggest this equation:
x+8x=45
9x=45
x=45/9
x=5

Sally´s strikers=x=5
Tami´s strikers=8x=8(5)=40

Answer: Sally have 5 strikers.

Difference between the amount Sally has and the amount that Tami has=
=5-40=-35
answer: the difference between the amount Sally has and the amount That Tami has is -35.


The negative sign indicates that she need 35 stickers, if she want to have the same amount that her friend.
