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
