Explanation Given: The equation of the system is x = 1 − y 2 x = z 2 z = − 2 − y . Approach: Gauss-Jordan method: 1. Write each equation so that variable terms are in the same order on the left side of the equal sign and constants are on the right. 2. Write the augmented matrix that corresponds to the system. 3. Use row operations to transform the first column so that all elements except the element in the first row are zero. 4. Use row operations to transform the second column so that all elements except the element in the second row are zero. 5. Use row operations to transform the third column so that all elements except the element in the third row are zero. 6. Continue in this way, when possible, until the last row is written in the form [ 0 0 0 ⋯ 0 j k ] , where j and k are constants with j ≠ 0 . When this is not possible, continue until every row has more zeros on the left than the previous row (except possibly for any rows of all zeros at the bottom of the matrix), and the first nonzero entry in each row is the only nonzero entry in its column. 7. Multiply each row by the reciprocal of the nonzero element in that row. Calculation: Consider the provided equation of the system x + y = 1 2 x − z = 0 y + 2 z = − 2 . Augmented matrix = [ 1 1 0 2 0 − 1 0 1 2 | 1 0 − 2 ] Now, use the Gauss Jordan method in which row operations are used to evaluated the solution of system. = [ 1 1 0 2 0 − 1 0 1 2 | 1 0 − 2 ] = [ 1 1 0 0 1 1 2 0 1 2 | 1 1 − 2 ] ( R 2 → R 1 − 1 2 R 2 ) <
