Best ResponseYou've already chosen the best response.0It doesn't have a solution 3(3x  2y) = 3(7) => 9x  6y = 21... Contradicts 9x  6y = 3. If you graph 9x  6y and 3x  2y, your lines will be parrallel. To graph it and see for yourself. Solve for y: 2y = 3  3x ... y = (3/2)  (3/2)x = (3/2)x  3/2 or 6y = 21  9x ... y = (7/2)  (9/6)x = (3/2)x  7/2 Notice they both have the same slope. Only the intercept differs.
