How can i view the graph of 3 variable equations in wolfram alpha?

I typed in wolfram alpha " solve 2x+y+z=5 , 4x-6y=-2 , -2x+7y+2z=9 " . It answered my question, but i would also like to see a graph of those equations, like a 3-d graph of those planes together. Can this be done only in the pro version? If not, must i type in something different to do that?
