  In the question there’s a symbol that looks like “^” but over a number. What does this mean?

  Regarding the short ending question:

  When I multiplied and added choice iii) as recommended by the answer:
  5(x + 2y - 3z = 4)

  3(-3x - y +5z = 6)

  I got: -4x + 7y = 38, not -4x + 7y = 29 as marked on the answer choice (in the video).

  Am I missing something obvious that I did wrong?

  wouldn't s (s = # + z) be the smaller root, and r (r = # - z) be the larger root?
