It can be shown that a solution of the system below is x 1 = 3, x 2 = 2, and x 3 = −1. Use this fact and the theory from this section to explain why another solution is x 1 = 30, x 2 = 20, and x 3 = −10. (Observe how the solutions are related, but make no other calculations.) x 1 − 3 x 2 − 3 x 3 = 0 − 2 x 1 + 4 x 2 + 2 x 3 = 0 − x 1 + 5 x 2 + 7 x 3 = 0
