( 9 − p ) ( 9 − q ) ( 9 − r ) ( 9 − s ) = 9. What is the value of p + q + r + s ?
cluponka [151]

p(r + s) = 5 and q(r + s) = 3.

by simply addind those two equations.

p(r + s) + q(r + s) = 5 + 3

(p + q) (r + s) = 8                 Statement #2: (p + q) = (r + s)

(p+q)×(r+s)=(p+q)×(p+q)=(p+q

it's been said it's not allowed us to arrive at a specific numerical value. The statementby itself inadequate.
