## anonymous one year ago MEDAL! Please explain clearly, step by step how to do this! Solve for x. 5a/x = 5b/x-1

• This Question is Open
1. pooja195

$\huge~\rm~\frac{ 5a }{ x}=\frac{ 5b }{ x-1}$

2. pooja195

like that?

3. anonymous

@pooja195 Yeah! :)

4. pooja195

Do you know where to start? :)

5. anonymous

Don't I cross multiply?

6. pooja195

yes! :) set uo the equation u get once you do that

7. anonymous

5a(x-1) = 5b(x) Is this right so far? Or am I way off...?

8. pooja195

good continue

9. anonymous

Whats the next step?

10. pooja195

5a(x-1) distribute

11. anonymous

How do I do that? I'm sorry I just suck at math... Every other subject are A's! XD

12. pooja195

$\huge~\rm~5a~\times~x=?$ $\huge~\rm~5\times-1=?$

13. anonymous

5ax and 4x?

14. pooja195

we are multiplying so it would be -5 5ax−5a=5bx

15. pooja195

what do u do from here?

16. pooja195

need help ?

18. pooja195

hmm :/ im not sure where to go from here maybe @mLe can help ;-; ?

19. mLe

get all the terms that have x in it alone to one side

20. mLe

subtract 5bx from both sides

21. mLe

and add 5a to both sides

22. mLe

then move the x out to the front ... opposite of distributing... for example if I had 7xy + 9xz I would get x (7y + 9z) then divide both sides by the stuff in the parenthesis to get it alone
