Find the ordered triple (p,q,r) that satisfies the following system:

p - 2q = 3

q - 2r = -2 + q

p + r = 9 + p

p + r = 9 + p, subtract p from both sides, you get r = 9.

q - 2r = -2 + q, subtract q from both sides, you get -2r = -2, r = 1. 

1 is not equal to 9, so there may be a latex or copy and paste issue when transferring websites frown
