The number of elements in the set {(a,b):2a^(2)+3b^(2)=35,a,b,inZ} , where Z is set of all integers is

For set {(a, b) : 2a^(2)+3b^(2)= 35, a, b in Z} the number of its elements is………..

Let Z denote the set of all integers and A = { (a,b) : a^2 +3b^2 = 28 ,a,b in Z } and B= {(a,b ):a gt b, in Z} . Then the number of elements in A nn B is

Let Z be the set of all integers and A={(a,b):a^(2)+3b^(2)=28,a,b in Z)B={(a,b):a>b,a,b in Z} Then,the number of elements in A nn B, is
