Sally and tami have 45 stickers. Tami has 8 times as many stickers as sally. How many stickers does sally have? What is the difference between the amount sally has and the amount that tami has?

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.
