When
, and thus (7,-1) is not solution of the equation.
B. (-1,7)
When
, and thus (-1,7) is a solution of the equation.
C. (0,5)
When
, and thus (0,5) is a solution of the equation.
D. (2,3)
When
, and thus (2,3) is a solution of the equation.
E. (3, 2)
When
, and thus (3,2) is not part of the solution
F. (5,0)
When
