Solve each equation for m and see which gives an answer of zero.
One is an identity with infinite solutions
One is a false statement with no solutions.

Rearrange each equation, using normal algebra rules, to solve for m. Only one of the equations will lead to a solution, and it will be m = 0. That is what you are calling "Solution set: Ø "
All the fancy talk about solution sets just makes the question look harder than it really is.
