…If they are over the same number multiply by it
1+4k-4-10k

-6k-3
-6k-1

Hmm. Did you copy the expression correctly? I’m seeing
(-5/k) where you have (-4/k) in the numerator, and (2/k) where you have (-4/k) in the denominator (and +3 instead of +4).
Anyways, I end up with (-6k-4)/(-7k+5).
Or, after factoring and canceling out a
-1, (6k+4)/(7k-5)
And, 5/7 is not in the domain.
Not sure if that all that’s being looked for, but there it is. And if I messed up, I’m sure someone will let me know.
well here goes:
TUESDAY-297=9?
Hope this helps
