# Using Wolfram Alpha For Solving A System Of Equations

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. $$\left.\begin{matrix} 2x - y +0z = 0\\ -x + 2y -z = -1\\ 0x - 3y + 4z = 4 \end{matrix}\right\}$$

As far as I know those functions are yet to be implemented for systems of equations. –  Listing Dec 26 '11 at 11:12
This works nicely. –  Ｊ. Ｍ. Dec 26 '11 at 11:33
If you enter "equations", you get this. –  Pierre-Yves Gaillard Dec 26 '11 at 11:42
just writing "$2x - y +0z = 0, -x + 2y -z = -1, 0x - 3y + 4z = 4$" gives $(0,0,1)$ as noted under the "examples" which seems to constitute the whole help structure –  yoyo Dec 26 '11 at 14:41

This seemed to work : solve(2x−y+0z=0,−x+2y−z=−1,0x−3y+4z=4,[x,y,z])

The syntax is Solve[{2 x - y == 0, -x + 2 y - z == -1, -3 y + 4 z == 4}, {x, y, z}] –  user13838 Dec 26 '11 at 13:40
This is what i get wolframalpha.com/input/… Doesn't seem to work! –  alok Dec 26 '11 at 14:39
@alok Remove the .Nope in the end and it works. –  user13838 Dec 26 '11 at 16:01

In WolframAlpha's Search Bar:

Search for "solve system of equations." Enter your equations.

Nice and useful! –  Goos Dec 18 '13 at 23:28
