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 first and second equations, then the second and third equations.
3x – 7y – z = –14
3x + 3y + 2z = 1
2x + 5y – 2z = –16
3x – 7y = –14
2x + 5y = –16
9x – 11y = –27
5x + 8y = –15
9x – 11y = –27
3x – 7y = –14
2x + 5y = –16
5x + 8y = –15
