Question

Which of the following equations has the given solution set?

Solution set: Ø

-2m + 5 = 2m + 5
-2m + 5 = -2m + 5
-2m + 5 = -2m - 5

Answer 1

Answer: -2m + 5 = -2m - 5 (C)

Explanation: Think this; why would two equations that are nearly identical come with the same result despite using different operations? An example of this sort of equation would be 2 + 2 = 2 - 2. Does 4 equal 0? No. In other words, you have no solutions.

Hope this helps! Happy Halloween...

Answer 2

-2m + 5 = -2m - 5
-2m + 2m = -5 - 5
0 = -10
which is no solution.

Therefore, the required equation is -2m + 5 = -2m - 5
