Question

PLEASE HELP?! :D


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.

x + y – 3z = –8
2x + 2y + z = 12
3x + y – z = –2

x + y = –8
3x + y = –2

x + y = –8
5x + 3y = 14

7x + 7y = 28
3x + y = –2

7x + 7y = 28
5x + 3y = 10
