In any word problem, our first step is to choose a variable letter to represent an unknown quantity. It is helpful to write in words that the variable is meant to stand for. From there, we set up an equation, and it's OK if the variable occurs in more than one place. Then we simplify each side of the equation as much as we can by combining like terms before solving. At the end, make sure your answer makes sense, and make sure you're answer the question that the problem has asked. Remember to add units to your answer if appropriate.
