- Matrix Representation In Exercises 49 and 50, assume that the matrix is the augmented matrix of a system of linear equations, and a determine the number of equations and the number of variables, and b find the values of k such that the system is consistent. Then assume that the matrix is the coefficient matrix of a homogeneous system of linear equations, and repeat parts a and b. A=[13k421]arrow_forwardSolving a Linear System Using LU-Factorization In Exercises 47 and 48, use an LU-factorization of the coefficient matrix to solve the linear system. 2x+y=1 y-z=2 -2x+y+z=-2arrow_forwardWriting an Augmented Matrix: In Exercises 15-20, write the augmented matrix for the system of linear equations. xy+2z=24x3y+z=12x+y=0arrow_forward
