p - 2q = 3

q - 2r = -2 + q

p + r = 9 + p

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

p - 2q = 3   

q - 2r = -2 + q   

p + r = 9 + p    

 

from q – 2r = –2 + q    we find that r = 1   

from p + r = 9 + p        we find that r = 9    

 

Since r can't equal both 1 and 9    

the system has no solution.
