12x / x-1 - 12 / x-1 i think i have the answer but want to be sure

You already know the common denominator: x-1
So
12x / x-1 - 12 / x-1 =
(12x - 12) / (x-1) =
12(x-1)/(x-1)
You can cancel out (x-1) because it appears on the top and on the bottom so the answer is just
12
Hope this helps.

(12x-12)/(x-1)= [12(x-1) ]/ (x-1) = 12

12x / x - 1=
12x - 12 / x - 1 =
12(x - 1) / x - 1
The x - 1 cancell

the answer is 12 because if you take out 12 and (x-1) common from numerator and denominator respectively then you will be left with (x-1) and after cancelling out you will be left with 12
Good Day

12x / (x - 1) - 12 / (x - 1)
= (12x - 12) / (x - 1)
= 12(x - 1) / (x - 1)
= 12
