4 b] If Show that

10 c] Solve the system of equations by Gauss elimination method2x+y+4z = 124x+11y-z= 338x-3y+2z = 20

10 b] Test for consistencyx-2y+3z = 23x-y+4z= 42x+y-2z = 5 and hence solve

10 a] Solve the following system of equation by Gauss-Seidel method:20x+y-2z = 173x+20y-z = -182x-3y+20z = 25
