-15k -15k
180=-3k
180/-3=k
-60=k
The answer the computer gives is -300 but I don't get that answer no matter what and can't really see how it gets it in the break down either.

You were going along sort of ok, but I don't understand why you did this:
\frac{3k}{25}\ +\ 36\ =\ \frac{12k}{25}(25))
That extra factor of 25 in the RHS does not belong there. I'm going to start over:
Add -44 to both sides
Add 
to both sides
LCD is 25
\frac{3k}{5}\ -\ \frac{12k}{25}\ \ =\ -36)
Combine like terms in the LHS:
Multiply by 25
Multiply by

My calculator said it, I believe it, that settles it
