Answer:

How To: Given a system of equations, write an augmented matrix.

Write the coefficients of the x-terms as the numbers down the first column.

Write the coefficients of the y-terms as the numbers down the second column.

If there are z-terms, write the coefficients as the numbers down the third column.

Draw a vertical line and write the constants to the right of the line.

Example 1: Writing the Augmented Matrix for a System of Equations

Write the augmented matrix for the given system of equations.

x+2y−z=3 2x−y+2z=6 x−3y+3z=4Solution

The augmented matrix displays the coefficients of the variables, and an additional column for the constants.

⎡⎢⎣12−12−121−33 | 364⎤⎥⎦ hope this helps lol :)
