-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
