Solve the system of linear equations
10x – 3y + 2z = 0
19x - 5y – z = 0

answer:

for 10x-3y+2z=0 is; x=3/10y-1/5z

                              y=10/3x+2/3z

                              z=-5x+3/2y

now for 19x-5y-z=0; x=5/19y+1/19z

                                  y=19/5x-1/5z

                                    z=19x-5y
