Can anyone solve my PDE equation?

[mazen.azhari]

i have this 2 equation to be solved, can someone help me with it please?
1- let m= m(x;y;z)
solve2((d^3/dx^3)+3(d/dx)(d^2/dy^2)-(d/dx)(d/dy))*m(x;y;z)=0

2-let m=m(x;y;z) solve (ydx+ydz)*m=m

I don't really know. But if you categorize it by order, linearity, homogeneity, etc. then you can look up techniques for solving that particular type of equation.

Oh, solve2? Are you using some software? Which software?
