Question: How to use PlanePlot (after with(Student[LinearAlgebra]) ) for 2 equations?..

Dear Maple experts,

 

I would like to visualize the equation -3*x+2*y+3*z=0  and (with other color) 2*y+3*z =0. I used the following commands:

with(Student[LinearAlgebra]):
infolevel[Student[LinearAlgebra]]:=1:
PlanePlot(-3*x+ 2*y + 3*z = 0, [x,y,z], normaloptions=[shape=harpoon], showbasis);

But I do not know how to show at the same time the second equation (2*y+3*z=0 ).

 

How should I proceed? Any hint?

Thanks for your attention,

 

Jean-Jaques
