This one appears a bit tricky. We have two equations and two unknowns:
step 1: divide the first equation by y and the second equation by x.
step 2: multiply the first equation by -1 and add the two equations together.
step #3: We can take the absolute value of both sides. absolute value (x-y) = 94/x - 19/y
I think this is what you are looking for?
