System of equations: 3x − y + z = 1 3x + 6y + 2z = 0 3x + 3y + 7z = 4 Iteration Formulas (for calculator): A = 1/3(1 + Y − M) : B = 1/6(−3X − 2M) : C = 1/7(4 − 3X − 3Y) Press CALC to perform iterations until four decimal places. This method is important in chemical engineering and other engineering applications where iterative solutions of linear systems are required. Try it yourself on your fx-991ES Plus calculator!
