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)

A 7x – 3z = 4
12x – 9z = 3

B 7x – 3z = 4
4x – 6z = 3

C 3x + 3z = 1
12x – 9z = 3

D 3x + 3z = 1
4x – 6z = 3

Answer 1

A, want to see the process?

Answer 2

well the answer is A anyway...
