Step Things to remember What to do in the equation Step 1: Identify the variables Variables represent values that can change. There may be one, two or several in a word problem. Write letters for the variables that will help you remember what they represent Step 2: Identify the end result of the situation. The end result may be a variable (if you don’t know the value) or a number (if the value is given). Put the end result after the equal sign. Step 3: Identify any constants. A constant is a value that will stay the same no matter what the variables are. Figure out if the constant is being added to or subtracted from the total. Add or subtract the constant(s). Step 4: Identify the rate(s) of change. The rate of change is how much the total will change each time the variable changes. In a linear equation, the rate of change will remain steady. Multiply the rate of change by the variable(s).
