6. JenniferSmart1

what is 3 times 3?

7. wabbit1993

9

8. JenniferSmart1

ok so we now have $9+x=15$ how do we get the 9 to the other side of the equal sign?

9. JenniferSmart1

make a guess

10. wabbit1993

i really don't know :/ i have been out of math for 3 years now. :(

11. JenniferSmart1

no problem

12. JenniferSmart1

we would subtract 9 from both sides to get x by itself so $\cancel{9-9}+x=15-9$

13. JenniferSmart1

Yes! Good job!
