Strategy Summary: Equation Solving
Step 1: If there are parentheses in the problem, eliminate them by use of the distributive property.
Step 2: Combine like terms (if possible) on each side of the equal sign.
Step 3: Using the "principle of opposites," get all variable terms to one side of the equation.
Step 4: Using the "principle of opposites," get all number terms to the other side of the equation.
Step 5: Divide both sides of the equation by the coefficient of the variable--that is, the number times the variable. (Or multiply both sides times the reciprocal of the coefficient.) If the coefficient is positive, divide by a positive number. If the coefficient is negative, divide by a negative number. The coefficient of the variable MUST be a positive one (+1) when you are through.
