# Solving a First-Order System of PDE's

## Solving a First-Order System of PDE's

(OP)
Hi guys, I am trying hard to solve a First-Order System of 2 Partial differential Equations using MathCAD14.
I have 2 function: M(x,y) and N(x,y); 2 partial DE's:
Mx = M - N and Ny= N - M;  and Boundary conditions: M(x,0)=a, N(0,y)=b, and M(0,x)=d; Could anyone help me solving this system?
Thanks

Is this school work?

Post on the real collab with a good attempt at a worksheet saved in V11 and someone will help.
