Setting up systems of equations to solve word problems.

• How do you solve a word problem using systems of equations?
• How do you set up a system of equations from a word problem?
• How do you check your answer to a system of equations word problem?
• If 2 CDs and 4 DVDs cost \$40, and 3 CDs and 5 DVDs cost \$55, how much does a CD cost and how much does a DVD cost?
• How do you solve the system of equations 2C + 4D = 40 and 3C + 5D = 55?
• If the sum of two numbers if 76 and their difference is 52, what are the two numbers?
• If you know the sum and the difference of two numbers, how can you find the two numbers?
• If x + y = 76 and x - y = 52, what do x and y equal?
This lesson looks at word problems that can be solved using systems of equations. Systems of equations are set up from the problems, solved, and checked. The concept of going from words to algebraic equations can often be a difficult one for students.
