3. A literal equation is an equation involving two or more variables.
Formulas are special types of literal equations.
To transform a literal equation, you solve for one variable in terms of the others.

9. Sometimes an equation will only have variables
Sometimes an equation will only have variables. Transforming this type of equation is no different from the previous examples.

10. Now you try:
Solve m – hp = d for p.

13. Now you try:
You can use the number of chirps n a cricket makes in one minute to estimate the outside temperature F in degrees Fahrenheit.
Transform the formula F = n/ to find the number of chirps in terms of temperature. How many chirps per minute can you expect if the temperature is 60 degrees Fahrenheit?
