How to solve a simultaneous equations

WebHow can I solve simultaneous equations on the TI-83 Plus and TI-84 Plus family of graphing calculators? Simultaneous equations can be solved by entering the coefficients of the equations in a matrix, and then using the rref() function on your matrix. For Example: Solve for x and y 3x + -2y = 12 6x + 4y = -3 Solution: First, begin by inputting ... WebOne way you can do that is by multiplying the top equation by 5 and multiplying the bottom equation by 3 because then, you could easily cancel out the 15 (top equation) and the -15 (bottom equation) and solve the rest of the equation accordingly. >>> 5x + 3y = 12 4x - 5y = 17 5x + 15y = 12 4x - 15y = 17 5x = 12 4x = 17 9x = 29 x = ~3.22 (Then ...
