If you were to use the elimination method to solve the following system, choose the new system of equations that would result after the variable z is eliminated in the second and third equations, then the first and second equations.

5x + 2y + z = –2
3x + 4y + 3z = 2
–4x – 3y – 3z = 1

5x + 2y = –2
3x + 4y = 2

–x + y = 3
–12x – 2y = 8

5x + 2y = –2
–12x – 2y = 8

x – y = –3
3x + 4y = 2
