Question 1168002: Find the multiplicative inverse of (7, -9)....where 7 is positive and 9 has a negative sign

I did it for (7,9) here yesterday:

If you can't make the few required sign changes from that one, then you don't
have the proper background for the course you're taking; you should drop the
course, and take a more basic algebra course.
