Use exact original integers a=0, b=0, c=-8 in a*x+b*y=c. The gcd d is nonnegative, and signed Bezout coefficients follow the deterministic extended Euclidean chain on absolute inputs, restoring input signs. For (a,b)≠(0,0), solvability is exactly d dividing c; finite searches do not supply all integer solutions. Handle (a,b)=(0,0) separately without division by d=0. Give (c, solvable, solution_set, boundary).

Definition and scope
Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Keep the historical interface marker in the original snapshot while listing ordered source fields here,without JavaScript or external lookup.Field labels are not mathematical evidence,and No retains the operation's claim scope.
ACTUAL original equation0*x+0*y=-8;BOTH coefficients0
After
left side is0 for EVERY integer pair;solvable iff c=0=No;solution set=no_integer_solution;NO gcd0 division
Conditions: none
With both coefficients zero the left side is identically0.For c=0 all of Z² solves it,not one parameter line;otherwise none does.Never divide by or reduce modulo gcd0.
S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
Result
(-8, No, no_integer_solution, never_divide_by_gcd_zero)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
