Explanation Calculation: Consider the system of equations 2 x + 13 y + 6 z = 1 3 x + 10 y + 11 z = 15 2 x + 10 y + 8 z = 8 We need to convert this system into triangular form: Here we no need to interchange the equations. 2 x + 13 y + 6 z = 1 2 ( x + 13 2 y + 6 2 z ) = 1 x + 13 2 y + 6 2 z = 1 2 The equation is already has a leading coefficient of 1. To eliminate x, multiply equation 2 x + 13 y + 6 z = 1 with -3 and equation 3 x + 10 y + 11 z = 15 with 2 and then add to equation 3 x + 10 y + 11 z = 15 − 6 x − 39 y − 18 z = − 3 6 x + 20 y + 22 z = 30 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ − 19 y + 4 z = 27 − 19 ( y − 4 19 z ) = 27 y − 4 19 z = − 27 19 To eliminate x, from equation 2 x + 13 y + 6 z = 1 To solve equation x + 3 y + 3 z = 4 and equation 2 x + 5 y + 4 z = 5 Multiply equation 2 x + 13 y + 6 z = 1 with −1 and then add both equations 2 x + 10 y + 8 z = 8 − 2 x − 13 y − 6 z = − 1 2 x + 10 y + 8 z = 8 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ − 3 y + 2 z = 7 y − 2 3 z = − 7 3 To eliminate y, from equation y − 4 19 z = − 27 19 Multiply equation y − 4 19 z = − 27 19 with −1 and then add both equations y − 2 3 z = − 7 3
