Solve e=mc2

$$e = m c 2$$

Solve for c_2

$$c_{2}=\frac{e}{m}$$

$$m\neq 0$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$mc_{2}=e$$

Divide both sides by m.

$$\frac{mc_{2}}{m}=\frac{e}{m}$$

Dividing by m undoes the multiplication by m.

$$c_{2}=\frac{e}{m}$$

Solve for m

$$m=\frac{e}{c_{2}}$$

$$c_{2}\neq 0$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$mc_{2}=e$$

The equation is in standard form.

$$c_{2}m=e$$

Divide both sides by c_{2}.

$$\frac{c_{2}m}{c_{2}}=\frac{e}{c_{2}}$$

Dividing by c_{2} undoes the multiplication by c_{2}.

$$m=\frac{e}{c_{2}}$$
