Eliminating the congruency of modular math problem

Is it possible to eliminate the congruency of a modular math problem. For the equation z=(2x+y)Mod 9, y can be either 7 or 8, and x is a member of the set of integers such that 0 ≤ x ≤ 8. How do we find the exact values of y and x for a given value of z For example, for z=(2x+y)Mod 9, if z = 0, then x could be ...continues
