Question 332650: Use the Gauss-Jordan Method to solve the system of equations.
x = 1 - y
2x = Z
2z = 2 - y
I am really confused by this totally and really have no idea where to start. Can someone help please.

You can put this solution on YOUR website!


First put your equations into standard form:









Then create a 3 X 4 matrix of the coefficients.



Manipulate the matrix to obtain:



















The last two steps are:





I'll leave the application of the last two steps to the matrix in your now very capable hands.
