CONCEPT:Gauss Seidel Method:In Gauss Seidel method, the value of x calculated is used in NEXT calculation putting other VARIABLE as 0.2x - 5Y + 3z = 7Putting y = 0, z = 0 ⇒ x = 3.5x + 4y - 2Z = 3Putting x = 3.5, z = 0 ⇒ y = - 0.1252x + 3y + z = 2Putting x = 3.5, y = - 0.125 ⇒ z = 2 – 3(-0.125) – 2(3.5)z = - 4.625
