y= 1/4x -3
Rewrite things as
and the matrix is
(1 -4 | 12)
(3 1 | 5)

Use Cramer's rule to determine if the system is inconsistent system or contains dependent equations. 2x + y = 8 6x + 3y = 24 A. system is inconsistent B. system contains dependent equations b ?
Explain the notation M^-1 used for the inverse of a square matrix M. I thought M^-1 would be a normal inverse matrix except the numbers would be vertically switched like in fractions...? Not sure though.
Write the augmented matrix, and then solve the system, using Gauss Jordan elimination on the augmented matrix. x + 2y - z = 4 -2x + y - 4z = -6 4x - 3y + 2z = -10
