Solving Literal Equations

A board with a rectange, the formula for area, and w = ? written on it.

During this topic, you investigated the properties of equality.  You also explored literal equations and learned how to apply the properties of real numbers and the properties of equality to solve these equations for specified variables.  Think back to the question presented in the introduction of this topic.  Can you explain the operation you must perform to solve the equation A = lw  for w?
