Since the choices are not defined, here's an example.
This Equation Has No Solution
[tex]5x + 6 = 5x - 3 \\ 5x + (6 - 6) = 5x - (3 - 6) \\ 5x = 5x - 9 \\ (5x - 5x) = (5x - 5x) - 9 \\ 0 = 0 - 9 \\ 0 = - 9 \\ 0 \: does \: not \: equal \: - 9[/tex]
Since, 0 does not equal -9, this is no solution, IF our results were 7=7 then we would have infinite solutions.
