-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

Subtract 7 from both sides
-2m = 11 - 7
Simplify 11 - 7 to 4
-2m = 4
Divide both sides by - 2
m = - 4/2
Simplify 4/2 to 2
m = - 2
