Juanita wants to perform row operations on the augmented matrix for the system below (see pictures). which matrix should juanita use to perform the operations?

The second option

Step-by-step explanation:

The given system of equation is

x+2y=3

-x+y+z=2

y-2z=-3

The augment matrix is obtained by combining the coefficient matrix with the constant matrix to obtain;

Note that the absence of z, in the first equation means its coefficient is zero. The same thing applies to x in the last equation.

The correct choice is the second option.

2/3

step-by-step explanation:

r = 78539458390583095803458309458039485093485 or just 3
