Solve 4.000cm=4m

$$4.000 cm = 4 m$$

Solve for c

$$\left\{\begin{matrix}\\c=1\text{, }&\text{unconditionally}\\c\in \mathrm{R}\text{, }&m=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Cancel out 4 on both sides.

$$cm=m$$

The equation is in standard form.

$$mc=m$$

Divide both sides by m.

$$\frac{mc}{m}=\frac{m}{m}$$

Dividing by m undoes the multiplication by m.

$$c=\frac{m}{m}$$

Divide m by m.

$$c=1$$

Solve for m

$$\left\{\begin{matrix}\\m=0\text{, }&\text{unconditionally}\\m\in \mathrm{R}\text{, }&c=1\end{matrix}\right.$$

Steps for Solving Linear Equation

Cancel out 4 on both sides.

$$cm=m$$

Subtract m from both sides.

$$cm-m=0$$

Combine all terms containing m.

$$\left(c-1\right)m=0$$

Divide 0 by -1+c.

$$m=0$$
