can someone show me step by step how to do this?
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
