Question

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

Answer 1

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

Answer 2

-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
