Write the pair of integers x and y, (x,y) in such a way that `x+y=-7`.

The pair of equtions x=0 and y=-7 has

Q) The number ofpositive integer pairs (x,y) such that (1)/(x)+(1)/(y)=(1)/(2007),x

If 8^(x^y)=4096 where x and y are positve integers and x ne 1 , then show that either x=y or x gt y .

Let f(x)=(ax)/(bx+3). where a,b in{y:|y|<6,y~ is~ integer}.~ Then~ write~ the number of possible...ordered pairs (a,b), such that f(f(x)=x

The number of ordered pairs of integers(x,y) which satisfy x^3 + y^3 = 65 are

If x and y are real then the number of ordered pairs (x,y) such that x+y+(x)/(y)=(1)/(2) and (x+y)(x)/(y)=-(1)/(2) is

If y=0 then the number of values of the pair (x, y) such that x+y+x/y=1/2 and (x+y)x/y= -1/2 is:

If y!=0 then the number of values of the pair "(x,y)" such that x+y+(x)/(v)=(1)/(2) and " (x+y)(x)/(y)=-(1)/(2) is
