Question 778226
You ask for a solution or solutions to an equation with two variables.  This will have infinite solutions.  Either p is a function of y or y is a function of p.  You would then look for values for either p or y which the function cannot accept because of being undefined.  


As written given, {{{2y-1<>0}}} meaning {{{y<>1/2}}}; and {{{p<>1}}}.
