Solve y=(b*a/2)-h

$$y = ( \frac { b \times a } { 2 } ) - h$$

Solve for a (complex solution)

$$\left\{\begin{matrix}a=\frac{2\left(y+h\right)}{b}\text{, }&b\neq 0\\a\in \mathrm{C}\text{, }&y=-h\text{ and }b=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$\frac{ba}{2}-h=y$$

Add h to both sides.

$$\frac{ba}{2}=y+h$$

Multiply both sides of the equation by 2.

$$ba=2y+2h$$

Divide both sides by b.

$$\frac{ba}{b}=\frac{2y+2h}{b}$$

Dividing by b undoes the multiplication by b.

$$a=\frac{2y+2h}{b}$$

Divide 2y+2h by b.

$$a=\frac{2\left(y+h\right)}{b}$$

Solve for b (complex solution)

$$\left\{\begin{matrix}b=\frac{2\left(y+h\right)}{a}\text{, }&a\neq 0\\b\in \mathrm{C}\text{, }&y=-h\text{ and }a=0\end{matrix}\right.$$
