Solve a=r/2dquaddz

$$a = \frac { r } { 2 d } \quad d z$$

Solve for d

$$d\neq 0$$

$$a=\frac{rz}{2}$$

Steps for Solving Linear Equation

Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2d.

$$a\times 2d=rdz$$

Subtract rdz from both sides.

$$a\times 2d-rdz=0$$

Reorder the terms.

$$-drz+2ad=0$$

Combine all terms containing d.

$$\left(-rz+2a\right)d=0$$

The equation is in standard form.

$$\left(2a-rz\right)d=0$$

Divide 0 by -rz+2a.

$$d=0$$

Variable d cannot be equal to 0.

$$d\in \emptyset$$

Solve for a

$$a=\frac{rz}{2}$$

$$d\neq 0$$
