Show that (2^x-10)/(10^(x-1)-5^x) can be reduced to 10/5^x

Anyone can help? I need to show the steps.

10^(x-1) = 5^(x-1) X 2^(x-1)

now start with denominator, taking out the common factor...

= (10^x / 5^x) - 10

(10^x/10) - 5^x

= 10/5^x

now how to do the top? i got the bottom

nvm. thx. its better i figure out from here myself.

i alr wrote it out.. should be pretty easy to figure
