\

The system of equations are \"\".

\

To write the augmented matrix,

\

Place the coefficients of the equations and the constant terms into matrix.

\

\"\". \"\"

\

\

To make the first element in the second (\"\") row a 0, multiply the first row (R1) by negative 3 and add the result to row 2(\"\").

\

\"\"   (The result is placed in row 2) \"\"

\

To make the second element in the first (\"\") row a 0, add the rows together, the result to row 1(\"\").

\

\"\"      (The result is placed in row 1)

\

The first row will give you the solution for \"\".

\

The second row will give you the solution for \"\".\"\"

\

The solution is  \"\".
