For what value K
is the following system consistent?
Source: Terry Stickel, Challenging Math Problems, 2015
This is really just a system of 3 equations and 3 unknowns, presented as if there were two variables (p,q) and k is some extra parameter.
Charlie already gave a nice solution, but here's a nice graph where you can alter k to make the three lines cross at a single point.
