B.There is no solution.

C.There are an infinite number of solutions.

D.The solution is (8, 1).

Respuesta :

the answer A.the solution is (5,-2) definitely works because 5+-2=3 and 5--2=7 not sure if there's infinite number of solutions tho

i know this is late but this man is right i double checked with k12 and its (5, -2)
