Which of the following equations has the given solution set?

Question

Solution set: Ø

1. -2m + 5 = 2m + 5

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

3. -2m + 5 = -2m - 5

Answer 1

1) The answer is m = 0

2) This is a statement of fact.

3) In this case, adding 2m to both sides of the equation you get

5 = -5    This is clearly not true.

The answer is #3

Answer 2

number 2

Answer 3

the answser is number 3. Never will (-2m +5) equa (-2m -5) . remember you can always check the other answers when its multiple choice. tons of #'s work for 2, and 0 works for #1.
