Solve fy=-3x+13

$$f y = - 3 x + 13$$

Solve for f (complex solution)

$$\left\{\begin{matrix}f=-\frac{3x-13}{y}\text{, }&y\neq 0\\f\in \mathrm{C}\text{, }&x=\frac{13}{3}\text{ and }y=0\end{matrix}\right.$$

Steps for Solving Linear Equation

The equation is in standard form.

$$yf=13-3x$$

Divide both sides by y.

$$\frac{yf}{y}=\frac{13-3x}{y}$$

Dividing by y undoes the multiplication by y.

$$f=\frac{13-3x}{y}$$

Solve for f

$$\left\{\begin{matrix}f=-\frac{3x-13}{y}\text{, }&y\neq 0\\f\in \mathrm{R}\text{, }&x=\frac{13}{3}\text{ and }y=0\end{matrix}\right.$$

Steps for Solving Linear Equation

The equation is in standard form.

$$yf=13-3x$$

Divide both sides by y.

$$\frac{yf}{y}=\frac{13-3x}{y}$$

Dividing by y undoes the multiplication by y.

$$f=\frac{13-3x}{y}$$

Solve for x

$$x=\frac{13-fy}{3}$$

Steps for Solving Linear Equation

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

$$-3x+13=fy$$

Subtract 13 from both sides.

$$-3x=fy-13$$

Divide both sides by -3.

$$\frac{-3x}{-3}=\frac{fy-13}{-3}$$

Dividing by -3 undoes the multiplication by -3.

$$x=\frac{fy-13}{-3}$$

Divide fy-13 by -3.

$$x=\frac{13-fy}{3}$$
