Answer:
4 possible values namely, (2 , 3, 6, 9 )
Step-by-step explanation:
When we factorise 54 we get,
[tex]54 = 2 \times 3 \times 3 \times 3 [/tex]
So, factors of 54 are, ( Except 1 and 54 (in pairs))
1. (2 , 27) Â 2. (3, 18) 3. (6 , 9)
So,
X  ∈ {2, 3, 6, 9}  but x ∉ { 27 , 18}  since y ∉ {2 ,3}
So, there are 4 possible values for x.
