(12C) Solve a system of linear equations of 2 Unknown
Solve a system of linear equations for two unknown variables.
This program solves for x and y, given the equation aX + bY = e cX + dY = f Remark: If "Error" show that indicate determinant D = 0, where D = ad - bc Example: X + Y = 10 X - Y = 4 1 ENTER 1 ENTER 10 R/S > 1,111,111,111 (Display First Equation Input) 1 ENTER 1 CHS ENTER 4 R/S > 2,222,222,222 (Display Second Equation Input) R/S > -2 D R/S > 7 (X) R/S > 3 (Y) Program: Code:
Example of the "No Solutions Equation" x - 2y = -4 -3x + 6y = 0 1 ENTER 2 CHS ENTER 4 CHS R/S > 1,111,111,111 3 CHS ENTER 6 ENTER 0 R/S > 2,222,222,222 R/S > 0 R/S > Error 0 This cause Error because each of the two lines has the same slope, 1/2, so the lines don't intersect. Gamo |
