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 2m + 5 = 2m + 5 Ermmm...WHAT? @Ashleyisakitty

    The answer, i believe, you are looking for is choice A. I plugged them all into my calculator and the only one to come up with a probably graph was A, and theta was only to do with graphs, so im assuming no other answer except A could work.

    Ashley...one more quick question... Which of the following would eliminate the variable on the left side of the given equation? 36 - 19w = -6w + 41 add 19w correct?

    empty set means there are no solutions the answer isn't choice A

    Yes one of the equations will lead to a no solution answer.

    -2m + 5 = 2m + 5 -2m + 5 = -2m + 5 -2m + 5 = -2m - 5 2m + 5 = 2m + 5 ----------------- Do you know about lines? Like you know parallel lines never intersect right? Parallel lines have the same slope but different y-intercept. Looking at both sides of the equation you have something like am+b (where a is the slope and b is the y-intercept) Do any of these have the same a on both sides but different b.

    Ok. Then solve equation equation for m. If you end up with something that can't be true in your eyes, then there is no solution. Like we know 1 doesn't equal 0. So if you end up with a situation like this, then you know there no solution. If we end up with something that is always true like 2=2 or 0=0, then there is infinite amount of solutions. There is the other case where we will end up with just the one solution. m=something.

    So when you solve the first equation for m, what do we get?

    -2m + 5 = 2m + 5 Get your m's on one side and your constants on the other side.
