How to use a system of equations to solve a word problem

The video tutorial guides students through solving a word problem by breaking it down into smaller steps. It emphasizes the importance of understanding the problem, identifying variables, and creating equations. The tutorial uses a hotel room problem to demonstrate how to set up and solve a system of equations, ultimately finding the number of rooms with and without kitchens.

What is the first step in tackling a word problem according to the speaker?

• Ignoring the problem

• Identifying what is being asked

• Solving equations immediately

• Guessing the answer

Why is it important to assign variables in a word problem?

• To confuse the solver

• To make the problem more complex

• To easily identify the unknowns

• To avoid solving the problem

What does the first equation in the problem represent?

• The number of rooms without a kitchen

• The number of rooms with a kitchen

• The total number of rooms

• The total revenue

How is the revenue equation set up in the problem?

• By subtracting the number of rooms without a kitchen from 200

• By multiplying the number of rooms with a kitchen by 100 and without by 80

• By adding the number of rooms with and without a kitchen

• By multiplying the number of rooms with a kitchen by 80

What is the final step in solving the system of equations?

• Ignoring the equations

• Assigning new variables

• Creating more equations

• Substituting and solving for one variable

What is the total number of rooms without a kitchen according to the solution?

• 200

• 50

• 150

• 100

How many rooms have a kitchen in the final solution?

• 200

• 150

• 100

• 50
