3x-3\left(m-3\right)=-6x
Multiply both sides of the equation by 2.
3x-3m+9=-6x
Use the distributive property to multiply -3 by m-3.
-3m+9=-6x-3x
Subtract 3x from both sides.
-3m+9=-9x
Combine -6x and -3x to get -9x.
-3m=-9x-9
Subtract 9 from both sides.
\frac{-3m}{-3}=\frac{-9x-9}{-3}
Divide both sides by -3.
m=\frac{-9x-9}{-3}
Dividing by -3 undoes the multiplication by -3.
m=3x+3
Divide -9x-9 by -3.
3x-3\left(m-3\right)=-6x
Multiply both sides of the equation by 2.
3x-3m+9=-6x
Use the distributive property to multiply -3 by m-3.
3x-3m+9+6x=0
Add 6x to both sides.
9x-3m+9=0
Combine 3x and 6x to get 9x.
9x+9=3m
Add 3m to both sides. Anything plus zero gives itself.
9x=3m-9
Subtract 9 from both sides.
\frac{9x}{9}=\frac{3m-9}{9}
Divide both sides by 9.
x=\frac{3m-9}{9}
Dividing by 9 undoes the multiplication by 9.
x=\frac{m}{3}-1
Divide -9+3m by 9.
