Hi there! I'm kind of confused about how to solve this!

Each ladder had 30 rungs.
Bob went down two rungs every second.
Roy went up one rung every second.
At some point, Bob and Roy were at the same height. Which rung were they on?

The answer is the 10th rung, but do I solve this using equal values, substitution, or the elimination method?
