5. LynFran

6. gabbyalicorn

hmm but I don't see how we can add multiply or subtract them since they all have different variables

7. LynFran

8. gabbyalicorn

|dw:1442027791898:dw|

9. LynFran

|dw:1442024241670:dw|

10. LynFran

now subtract 18 frm both sides of the equation

@gabbyalicorn do you know what you're doing, or rather, what "a" means?

15. gabbyalicorn

I thought we are still trying to find out what A means

16. LynFran

-6-18 isnt 12

17. gabbyalicorn

wait... are we doing -6 x -18?

18. LynFran

nope... -6 take 18 which =-24 |dw:1442024590966:dw|

20. Jhannybean

Not quite... how would you isolate a on one side? You would have to divide EACH side by 6.

22. Jhannybean

You're missing a sign, what is a negative divided by a positive?

23. gabbyalicorn

well in this case -24 is bigger than 6 so its -4

24. Jhannybean

Good job.
