Solution set: Ø

A)-2m + 5 = 2m + 5

B)-2m + 5 = -2m + 5

C)-2m + 5 = -2m - 5

One is an identity with infinite solutions

One is a false statement with no solutions.

**drwls**, Friday, March 5, 2010 at 6:43pmRearrange 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.
