Five Steps for Problem Solving Determine what you are asked to find and assign a variable to this unknown quantity. Read the problem carefully. Decide what is given and what must be found. Choose a variable for the quantity that must be known in order to answer the question and write down exactly what it represents: let x This step is the most important because it establishes your goall Organize and label all given or pertinent information. If there are other unknown quantities, express them using the variable. Draw figures or diagrams if they apply. Also, if a formula is to be used to relate the quantities from the problem, write it down here. Sometimes a chart with properly labeled columns and rows can be used to organize the given information, including the variable the formula, totals, etc. Assemble the equation. Write an equation, inequality, or system of equations to express the relationships among the quantities given in the problem. Solve the equation. Use the methods learned throughout the course to solve the equation, inequality, or system of equations State the answer to the question(s) posed by the problem. Reread the problem and make sure that you answer the question or questions posed. In some cases, you will need to give more than just the solution of the equation. State the answer using a complete sentence with the appropriate units. 1. 2. 3. 4. 5.
