a. Explanation Given: The system of three linear equations in three variables is, { x − y + 2 z = 12 y − z = − 5 x + 2 z = 10 . Calculation: Name the equations in the system as follows. x − y + 2 z = 12 (1) y − z = − 5 (2) x + 2 z = 10 (3) The coefficients of x , y and z and constant term for the equation (1) are respectively 1 , − 1 , 2 and 12 . The first three of these are the elements of Row 1 of the coefficient matrix and the last one is the element of Row 1 of the constant matrix. The coefficients of x , y and z and constant term for the equation (2) are respectively 0 , 1 , − 1 and − 5 . The first three of these are the elements of Row 2 of the coefficient matrix and the last one is the element of Row 2 of the constant matrix. The coefficients of x , y and z and constant term for the equation (3) are respectively 1 , 0 , 2 and 10 b. To determine To solve: The system using inverse matrix of the coefficient matrix.
