This program solves 'System of equations' (simultaneous equations). Press the green flag to start. Enter the coefficients (a, b, c, d, e and f) for both equations, and the program will solve your equations. eg. for the following equations: 3x + 5y = 34 & 4x + 3y = 27 enter a as 3; b as 5, c as 34, d as 4, e as 3 and f as 27
