## jamie2012 2 years ago 78 = -2(m + 3) + m

1. BlondeGirl

use distributive property first on -2(m+3)

2. BlondeGirl

let me know what you get and ill work with you from there(:

3. jamie2012

i don't get the distributive property. sorry

4. BlondeGirl

you multiply -2 to m and 3

5. BrittanyFrench

distribute the -2 by multiplying them to the m and 3 then you'll have your equation..

7. BlondeGirl

so you would have -2m-6

8. BlondeGirl

combine like terms now

9. BrittanyFrench

yeah

10. jamie2012

2m and m

11. BrittanyFrench

let me know what you get

12. BlondeGirl

exactly just combine those add 2m+1m

13. jamie2012

3m

14. BrittanyFrench

yeah so know whats your equation?

15. BlondeGirl

wait sorry i forgot it was negative lol it would be -m

16. jamie2012

so it would be -3m?

17. BrittanyFrench

yes little things we miss lol what's your equation now?

18. BlondeGirl

no you would have 78+-m-6

19. BlondeGirl

= not +

20. BlondeGirl

sorry my keyboard is funny

21. BrittanyFrench

okay i'm out, lol my brains not working. Good job though blondegirl

22. BlondeGirl

haha all you have to do is solve this one step equation now 78=-m-6 do you know how to do that?

23. jamie2012

would it be -81?

24. BlondeGirl

no you add 6 to 78 because you do the opposite of what the sign says since it is on the other side of the equals sign

25. jamie2012

84

26. BlondeGirl

exactly so it is 84= -1m or -84=m

27. BlondeGirl

28. jamie2012

29. BlondeGirl
