Solve dA=f

$$d A = f$$

Solve for A

$$\left\{\begin{matrix}A=\frac{f}{d}\text{, }&d\neq 0\\A\in \mathrm{R}\text{, }&f=0\text{ and }d=0\end{matrix}\right.$$

Steps for Solving Linear Equation

The equation is in standard form.

$$dA=f$$

Divide both sides by d.

$$\frac{dA}{d}=\frac{f}{d}$$

Dividing by d undoes the multiplication by d.

$$A=\frac{f}{d}$$

Solve for d

$$\left\{\begin{matrix}d=\frac{f}{A}\text{, }&A\neq 0\\d\in \mathrm{R}\text{, }&f=0\text{ and }A=0\end{matrix}\right.$$

Steps for Solving Linear Equation

The equation is in standard form.

$$Ad=f$$

Divide both sides by A.

$$\frac{Ad}{A}=\frac{f}{A}$$

Dividing by A undoes the multiplication by A.

$$d=\frac{f}{A}$$
