Exploring System of Equations in Word Problems

The video tutorial covers solving systems of equations through word problems. It begins with an introduction to the topic, emphasizing the importance of breaking down problems into manageable parts. The first example involves calculating the hourly pay of Judy and Ben using the elimination method. The second example focuses on determining the number of blue and red action figures purchased based on their total cost. The tutorial highlights strategies for setting up equations and choosing the most efficient method for solving them.

What is the first step the teacher suggests when dealing with word problems?

• Ask someone else to solve it

• Ignore the problem and guess the answer

• Read the problem and write it down

• Try to solve the entire problem at once
