  31. Unit 1 Outcome 5 GAUSSIAN ELIMINATION Past Paper 2002 Q1 5 marks Use Gaussian elimination to solve the following system of equations x +y +3z = 2 2x +y + z = 2 3x + 2y + 5z = 5 R2 –2R1 R3 -3R1 R3 –R2 y = -3 z = 1 -y –5z = -2 x - 3 +3 = 2 x = 2 -y = -2 +5 (x,y,z) = (2, -3, 1) St Joseph’s College

  32. Unit 1 Outcome 5 GAUSSIAN ELIMINATION Past Paper 2003 Q6 6 marks Use elementary row operations to reduce the following system of Equations to upper triangle form x +y +3z = 1 3x + ay + z = 1 x + y + z = -1 Hence express x, y and z in terms of parameter a. Explain what happens when a = 3 R2 –3R1 R3 -R1 R3/-2 z = 1 y = 6/(a-3) (a-3)y –8 = -2 x + 6/(a –3) + 3 = 1 x = -2 –6/(a-3) (a-3)y = 6 a=3 gives z = ¼ from R2 and z = 1 from R3. Inconsistent equations! St Joseph’s College

  33. Unit 1 Outcome 5 GAUSSIAN ELIMINATION Use Gaussian elimination to solve the system of equations below when . Past Paper 2005 Q6 6 marks x +y +2z = 1 2x +ly + z = 0 3x + 3y + 9z = 5 Explain what happens when l = 2 R2 –2R1 R3 -3R1 R3/3 z = 2/3 x = 1 –4/3 (l-2)y –2 = -2 x = -1/3 y = 0 l=2 gives R2 = R3. Infinite number of solutions! St Joseph’s College
