Question

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 y is eliminated in the first and second equations, then the second and third equations.
3x - y + 3z = 1
4x + y - 6z = 3
4x - 2y + 3z = -3 (4 points)
Answer

7x - 3z = 4
12x - 9z = 3

7x - 3z = 4
4x - 6z = 3

3x + 3z = 1
12x - 9z = 3

3x + 3z = 1
4x - 6z = 3
