## Josizzle98 3 years ago r= 2/3t+v , solve for t Show work please, I'm stressing out on some of these problems... thanks :)

1. godorovg

r=2/3t+v so to solve for T.. first take minus the V on both sides like this v-r=2/3t you following this??

2. godorovg

next because we are solving for T we divide by 2/3 to get T my itself. so we have v-r/2/3=t

3. godorovg

hope this helps...

4. Josizzle98

Thank you so much!

5. godorovg

not a problem any questions before I leave?

6. Josizzle98

I have one last problem thats bugging me and that is -14n+q=rt-4n, solve for n.

7. godorovg

first what do you know already

8. Josizzle98

do I need to subtract rt from both sides?

9. godorovg

yes you can do that, but we to collect a like terms first

10. Josizzle98

Oh! The -14n and the -4n can go together.

11. godorovg

yes, but be careful here what happens with the sign when it crosses the equal? recall + becomes - and - becomes +

12. Josizzle98

So, 18n+g=rt ?

13. godorovg

that is correct

14. godorovg

so now what do we need to get N standing alone?

15. godorovg

hint look at the g.

16. Josizzle98

subtract the g on both sides, leaving me with 18n=rt-g

17. godorovg

yes

18. Josizzle98

then divide by 18 to get n=rt-g/18 ?

19. godorovg

Nice job

20. Josizzle98

Thank you SO much! I understand it now! :D You're a lifesaver.

21. godorovg

I want to be sure you understand so ask questions if you have any?

22. Josizzle98

Okay, I have another problem that I know how to start off but not finish. ax+z=aw -y +y +y And that gives me ax+z+y=aw And thats where I'm not sure where to go from there...

23. godorovg

what are we solving for or what is the problem asking for?

24. Josizzle98

whoops. the equation is ax+z=aw-y, solve for a. You add y on both sides giving you ax+z+y=aw. And then I don't know what else to do.

25. godorovg

okay this one is more tricky, but do able

26. godorovg

first let's look at the a terms here? are alike? no, but what we can do is them on side.

27. godorovg

so you can do this ax+z+y=aw take the ax-aw and than take -z-y so you should have the following ax-aw=-z-y

28. godorovg

got it?

29. Josizzle98

yes.

30. godorovg

this is where it is tricky what can we do with the a's here?

31. Josizzle98

add the 2 a's to get 2a(wx)=-z-y ?

32. godorovg

try factoring an a.

33. godorovg

did you factor an A?

34. Josizzle98

I don't understand again..

35. godorovg

I have it 2a(wx)=-z-y ? from this point take the wx and divide by -z-y so therefore you would 2a=-z-y/wx next divide by 2 to get the a alone so you should have A=-z-y/2wx.

36. Josizzle98

Okay thank you so much! I understand it now! :D

37. godorovg

really make sure you understand ask questions plz if something isn't clear?
