Use row operations on augmented matrices to solve the given systems of linear equations?
1.

х+ у — х+ 2у + 3z %3D — 5 2х — у — 1323D 17 y – 13z =

2.

x+ 2y - z= 3 2x + 5y – 2z = -x + y+ 5z =-12

3.

+ + 2 + 3z %3D 5 2 1323D 17 y 13z

4.

= x+ 2y - z= 3 2x + 5y 2z = -x

+ + 2 + 3z %3D 5 2 1323D 17 y 13z = x+ 2y - z= 3 2x + 5y 2z = -x + y+ 5z =-12
