Question

MEDAL!
Please explain clearly, step by step how to do this!
Solve for x.

Answer 1

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

Answer 2

like that?

Answer 3

@pooja195 Yeah! :)

Answer 4

Do you know where to start? :)

Answer 5

Don't I cross multiply?

Answer 6

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

Answer 7

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

Answer 8

good continue

Answer 9

Whats the next step?

Answer 10

5a(x-1)
distribute

Answer 11

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

Answer 12

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

Answer 13

5ax and 4x?

Answer 14

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

Answer 15

what do u do from here?

Answer 16

need help ?

Answer 17

Yes please

Answer 18

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

Answer 19

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

Answer 20

subtract 5bx from both sides

Answer 21

and add 5a to both sides

Answer 22

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
