Let x be the number.

x = 9 - pq
is the equation needed.

If you want me to find a solution:
If p = 2
q = 4
x = ?
( ?, 2, 4)

Evaluate:
x = 9 - [(2)(4)]
x = 9 - [(8)]
x = 1

A solution set is: (x, p, q) = (1, 2, 4)

Another:
If x = 2
q = 4
p = ?

(2, ?, 4)
2 = 9 - 4p
2 - 9 = 9 - 9 - 4p
-7 = 4p
-7/4 = 4p/4
-7 / 4 = p

A solution set is: (x, p, q) = (2, -7/4, 4)
