Solve for m

3-2 (9+2m) = m

m=-3

Step-by-step explanation:

3-2 (9+2m) = m

3-2 (9) - 2 (2m) = m

3-18-4m=m

-15-4m=m

-15=m+4m

5m=-15

Divide by 5

5m/5=-15/5

m=-15/5

m=-3

To check if correct, subsitute m for - 3 in the equation. And both sides of the equation must be equal

3-2 (9+2m) = m

3-2 (9+2 (-3)) = -3

3-2 (9-6) = -3

3-2 (3) = -3

3-6=-3

-3=-3
