Why is it important to understand inverse operations?

• They are only relevant for addition and subtraction.

• They are not applicable in real-world scenarios.

• They help in solving complex equations.

• They are only used in basic arithmetic.

What is the first step in solving an equation with subtraction?

• Multiply both sides by the same number.

• Add the same number to both sides.

• Divide both sides by the same number.

• Subtract the same number from both sides.

What operation should be used to undo division in an equation?

• Addition

• Subtraction

• Division

• Multiplication

If a variable is divided by 20, what should you do to isolate it?

• Divide both sides by 20.

• Add 20 to both sides.

• Subtract 20 from both sides.

• Multiply both sides by 20.

What is the result of multiplying 20 by 1 in the context of solving the equation?

• 0

• 1

• 20

• 40
