Final answer:
To solve multiple logarithmic equations, find equations that contain only one unknown and an additional equation is needed if the equation contains more than one unknown. In some cases, multiple unknowns must be determined.
Step-by-step explanation:
To solve more than a single logarithmic equation, you will need to find equations that can help you solve the problem. It is easiest if you can find equations that contain only one unknown, so you can easily solve for the unknown. If the equation contains more than one unknown, then an additional equation is needed to solve the problem. In some cases, multiple unknowns must be determined to get the final answer, and you may have to use two or more different equations.
