Select ALL the systems that have the same solution as the following below. HINT: There are 3 correct answers

5x + y = 9

10x + 7y = −18

• 15x + 8y = -9

  20x + 14y = -36

• -10x - y = 18

  10x - 7y = -18

• 15x - 5y = -9

  10x - 7y = -18

• -35x - 7y = -63

  10x + 7y = -18

• -10x - 2y = -18

  10x + 7y = -18
