TITLE: Using Wolfram Alpha For Solving A System Of Equations
QUESTION [7 upvotes]: How do i input  the below system of equations in wolfram alpha in order to solve for the unknowns and plot them? If i just say "solve" and input these equations one after the other with a simicolen {solve $2x - y +0z = 0$;$-x + 2y -z = -1$;$0x - 3y + 4z = 4$} it simply throws the value of $x$,$y$ and $z$ without showing any steps nor the plot.
I'am Wondering if there's some kind of code that can be written in order to make wolfram alpha understand what i'am talking about.
$$\left.\begin{matrix}
 2x - y +0z = 0\\ 
-x + 2y -z = -1\\
 0x - 3y + 4z = 4
 \end{matrix}\right\}$$
