Solve lambda=0.693/20s

$$\lambda = \frac{ 0.693 }{ 20s }$$

Solve for s

$$s=\frac{693}{20000\lambda }$$

$$\lambda \neq 0$$

Steps for Solving Linear Equation

Variable s cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 20s.

$$\lambda \times 20s=0.693$$

Reorder the terms.

$$20s\lambda =0.693$$

The equation is in standard form.

$$20\lambda s=0.693$$

Divide both sides by 20\lambda .

$$\frac{20\lambda s}{20\lambda }=\frac{0.693}{20\lambda }$$

Dividing by 20\lambda undoes the multiplication by 20\lambda .

$$s=\frac{0.693}{20\lambda }$$

Divide 0.693 by 20\lambda .

$$s=\frac{693}{20000\lambda }$$

Variable s cannot be equal to 0.

$$s=\frac{693}{20000\lambda }\text{, }s\neq 0$$

Solve for λ

$$\lambda =\frac{693}{20000s}$$

$$s\neq 0$$
