Solve for x
x=\frac{m}{3\left(4-m\right)}
m\neq 4
Solve for m
m=\frac{12x}{3x+1}
x\neq -\frac{1}{3}

3\left(4-m\right)x-m=0
Multiply both sides of the equation by 3.
\left(12-3m\right)x-m=0
Use the distributive property to multiply 3 by 4-m.
12x-3mx-m=0
Use the distributive property to multiply 12-3m by x.
12x-3mx=m
Add m to both sides. Anything plus zero gives itself.
\left(12-3m\right)x=m
Combine all terms containing x.
\frac{\left(12-3m\right)x}{12-3m}=\frac{m}{12-3m}
Divide both sides by 12-3m.
x=\frac{m}{12-3m}
Dividing by 12-3m undoes the multiplication by 12-3m.
x=\frac{m}{3\left(4-m\right)}
Divide m by 12-3m.
