This document appears to contain examples of solving various mathematical equations. Example 3-1a shows dividing 180 by an unknown quantity and setting it equal to 100. Example 3-2a and 3-2b show solving inequality equations by dividing or multiplying both sides by the same quantity. Example 3-3a shows subtracting quantities from both sides of an equality. Example 3-4a shows subtracting a term from both sides of an inequality and then dividing both sides by the same quantity to isolate the variable.
