Solve the following equation for m -2m+7=11

-2m+7=11

you moved the 7 to the other side which means the sign changes so instead of a +7 it would be a -7 underneath the 11

-2m=11
-7

Then you subtract 11-7 so it would be a positive 4. its a positive because the 11 is greater than the -7.

-2m=4

You would have to divide the -2 on both sides so the m could be alone.

-2m/-2=4/-2

So the two negatives cancel each other out and 4/-2 would be a -2 so a negative and a negative would equal a positive

m=-2

Ibelieve the answer is a

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
