SYSTEMS OF EQUATIONS Gaussian Elimination (Page 1 of 13)

Let's solve the system of equations 2x-y+2z = -8; x+2y-3z = 9; 3x+11y-12z = 43 using Gaussian elimination. The augmented matrix for this system is matrix{row1: 2 -1 2 -8; row2: 1 2 -3 9; row3: 3 11 -12 43}. First enter the augmented matrix into the calculator using the matrix editor. We will use matrix A. (We are assuming matrix [A] has not yet been stored in the calculator. Click here to delete a previously created matrix.)
