How do I learn RPL and solve this problem with it?

I wouldn't be so sure it speeds up the problem. You'll be searching through a large list of pairs, which is not necessarily any faster than computing 4 or 5 values on the fly. It's just a couple of additions and divisions versus a long loop of comparisons (only subtractions in the end, but we could be talking in the hundreds until you find all the valid combinations through the list).
