19. Give the solution for a system with the augmented matrix shown below

%28matrix%282%2C4%2C1%2C0%2C%22%3A%22%2C2%2C+0%2C1%2C%22%3A%22%2C-3%29%29 is the augmented matrix
form of the system:

system%281x%2B0y=2%2C0x%2B1y=-3%29

which simplifies to

system%28x=2%2Cy=-3%29

18. Write the system of linear equations represented by the matrix equation shown below



is the matrix equation AX=B form of the system:

system%281x-1y%2B1z=1%2C+2x%2B1y%2B3z=-3%2C4x%2B2y-1z=2%29
 
Erasing the 1's

system%28x-y%2Bz=1%2C+2x%2By%2B3z=-3%2C4x%2B2y-z=2%29
