Solve y=kx+3

$$y = k x + 3$$

Solve for k (complex solution)

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

Steps for Solving Linear Equation

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

$$kx+3=y$$

Subtract 3 from both sides.

$$kx=y-3$$

The equation is in standard form.

$$xk=y-3$$

Divide both sides by x.

$$\frac{xk}{x}=\frac{y-3}{x}$$

Dividing by x undoes the multiplication by x.

$$k=\frac{y-3}{x}$$

Solve for x (complex solution)

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