- aExplain how Gaussian elimination works. bUse Gaussian elimination to put the following system in triangular form, and then solve the system. System Triangular form {x+y2z=3x+2y+z=53xy+5z=1arrow_forwardUse Cramers Rule to solve the system of linear equations for x and y. kx+(1k)y=1(1k)x+ky=3 For what values of k will the system be inconsistent?arrow_forwardThe systems in Exercises 25 and 26 exhibit a lower triangular pattern that makes them easy to solve by forward substitution. (We will encounter forward substitution again in Chapter 3.) Solve these systems. x1=112x1+x2=532x1+2x2+x3=7arrow_forward
