Question

Which of the following equations has the solution set {0}?

-14m - 7m + 1 = -7m + 1
-14m + 7m + 1 = -7m + 2
14m - 7m - 1 = -7m + 1

Answer 1

You should try to simplify them first. Get it?

Answer 2

Also do you have the options correctly?

Answer 3

yep

Answer 4

could you help explain it to me?

Answer 5

Yes i could. Im looking at it now, did you mean to write a 2 in the second option?

Answer 6

yeah i just copy and pasted it from my homework.

Answer 7

Then i don't think any of those has a solution of 0

Answer 8

But basically, what you have to do is to simplify both sides and add up to see which one will give you zero

Answer 9

my calc site said it would be the second one but doing it the way you said to gives me a different answer.
