This document discusses solving equations with mixed operations. It explains that the order of operations is SADMEP (Subtraction, Addition, Division, Multiplication, Exponents, Parentheses) and provides examples of solving equations step-by-step by combining like terms, moving terms to one side of the equation using inverse operations, and simplifying. The document provides examples of solving equations with variables like x, n, and examples of solving equations with mixed addition, subtraction, multiplication, and division terms.
