Solving Word Problems with Equations

In this video, Mr. Lindsay teaches how to write and solve two-step equations using a word problem. The lesson focuses on identifying key elements such as rate, variable, constant, and total in a word problem. A practical example involving the purchase of skibbidy toilets is used to demonstrate the process. The video provides a detailed, step-by-step guide to isolating the variable and solving the equation, ensuring students understand the method thoroughly.

What is the main focus of the lesson introduced by Mr. Lindsay?

• Understanding algebraic expressions

• Writing and solving two-step equations from word problems

• Learning about fractions and decimals

• Solving quadratic equations

Which of the following is NOT one of the four key elements to identify in a word problem?

• Total

• Coefficient

• Variable

• Rate

What does the term 'rate' refer to in a word problem?

• How fast or slow something changes

• The final result of a calculation

• A fixed number that doesn't change

• An unknown number

In the sample problem, what is the cost of each skibbidy toilet?

• $30.00

• $25.00

• $22.50

• $20.00

What is the one-time Phantom tax charged in the sample problem?

• $5.00

• $4.00

• $3.00

• $2.00

In the sample problem, what is the total amount spent at the store?

• $20.50

• $24.50

• $28.50

• $26.50

What does the variable 's' represent in the equation?

• The Phantom tax amount

• The total amount spent

• The number of skibbidy toilets bought

• The cost of one skibbidy toilet

What is the first step in solving the equation to find the number of skibbidy toilets bought?

• Add the rate to the total

• Subtract the constant from the total

• Multiply the rate by the variable

• Divide the total by the rate

What operation is used to isolate the variable 's' in the equation?

• Division

• Addition

• Subtraction

• Multiplication

How many skibbidy toilets did the BR and huz buy according to the solution?

• 10

• 9

• 8

• 7
