The solution was there...I forgot it. Had to do with some competition. With no background/information, such a puzzle is really almost impossible to solve. A bit like: c * 5 = 3 * 22 a to z = 1 to 26 c = 3rd letter of alphabet 5 = 5th letter from end of alphabet = v = 22

The third line is what confuses, as it ought to be something like "14 W 6 = 1, 8". Solving 5 W 10 gives 123 (which really ought to be written as "1, 3"). It could also be explained using inches and feet or anything else where 12 of one thing makes one of another.
