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
