HP Prime "Cannot Find Solution" when solving two equations

[ijabbott]

My guess is that on the HP 50g you would use the Multiple Equation Solver (MES) to solve those equations, but the HP Prime's Solver is used to solve a system of equations (simultaneous equations). They are not the same thing, and the equations you have are not a system of equations. The 50g's MES solves the equations one at a time, not simultaneously.
