1. Write a matrix representing the system of equations

x+2y+z=5

2x-y+2z=15

3x+y-z=8

Solve the system by transforming your matrix into reduced row echelon form. State the solution as an ordered triple.

2. Solve the system of equations by forming a matrix equation, then solve using inverse matrices. State your answer as an ordered pair.

x+2y=-7

-3x-5y=23

Appreciate any help!
