3-m=2\left(m+2\right)
Variable m cannot be equal to -2 since division by zero is not defined. Multiply both sides of the equation by m+2.
3-m=2m+4
Use the distributive property to multiply 2 by m+2.
3-m-2m=4
Subtract 2m from both sides.
3-3m=4
Combine -m and -2m to get -3m.
-3m=4-3
Subtract 3 from both sides.
-3m=1
Subtract 3 from 4 to get 1.
m=\frac{1}{-3}
Divide both sides by -3.
m=-\frac{1}{3}
Fraction \frac{1}{-3} can be rewritten as -\frac{1}{3} by extracting the negative sign.
