By the end of the lesson, viewers will understand how to balance equations and apply inverse operations to find unknown values.

What is the primary focus of this lesson on algebraic equations?

• Solving equations using inverse operations

• Understanding the concept of variables

• Learning about geometric shapes

• Solving equations using multiplication and division

What does a variable represent in an algebraic equation?

• An unknown number

• A geometric shape

• A mathematical operation

• A known number

Which of the following is an example of inverse operations?

• Multiplication and division

• Addition and subtraction

• Exponentiation and logarithms

• Sine and cosine

What is a common mistake when solving algebraic equations?

• Using the same operation on both sides

• Balancing only one side of the equation

• Using different variables

• Ignoring the coefficients

In the equation x - 10 = 15, what should be done to solve for x?

• Subtract 10 from both sides

• Divide both sides by 10

• Add 10 to both sides

• Multiply both sides by 10

How much money did Drew originally have if he spent $4 and has $15 left?

• $11

• $19

• $15

• $4

What equation represents Drew's spending problem?

• x = 15 - 4

• x = 4 + 15

• x - 4 = 15

• x + 4 = 15

How much money did Daisha have before receiving her birthday check?

• $75

• $148.50

• $73.50

• $223.50

What equation represents Daisha's birthday check problem?

• m + 75 = 148.50

• m = 148.50 - 75

• m = 75 + 148.50

• m - 75 = 148.50

What is the final step in solving the equation m + 75 = 148.50?

• Divide both sides by 75

• Multiply both sides by 75

• Subtract 75 from both sides

• Add 75 to both sides
