Find the value of the unknown that makes the equation [math]18=3\cdot y[/math] true.
You are walking down a road, seeking treasure. The road branches off into three paths. A guard stands in each path. You know that only one of the guards is telling the truth, and the other two are lying. Here is what they say:[br][br][list][*]Guard 1: The treasure lies down this path.[/*][*]Guard 2: No treasure lies down this path; seek elsewhere.[/*][*]Guard 3: The first guard is lying.[/*][/list][br]Which path leads to the treasure?
