What is the addition property of equality

The video tutorial explains the addition property of equality, which states that adding the same number to both sides of an equation results in equivalent equations. It demonstrates this concept with a simple example and further applies it to solve an equation, showing how the property helps in finding solutions.

What does the addition property of equality state?

• Dividing both sides of an equation by the same number keeps it equal.

• Adding the same number to both sides of an equation keeps it equal.

• Multiplying both sides of an equation by the same number keeps it equal.

• Subtracting the same number from both sides of an equation keeps it equal.

In the example 4 = 4, what happens when you add 1 to both sides?

• The equation becomes 4 = 5, which is false.

• The equation becomes 5 = 5, which is true.

• The equation becomes 5 = 4, which is false.

• The equation becomes 4 = 4, which is unchanged.

What is the solution for X in the equation X - 10 = 15 using the addition property of equality?

• X = 15

• X = 25

• X = 10

• X = 5

How do you verify that two equations are equivalent using the addition property of equality?

• By subtracting the same number from both sides.

• By adding the same number to both sides.

• By multiplying both sides by the same number.

• By dividing both sides by the same number.

What is the result of adding 10 to both sides of the equation X - 10 = 15?

• X = 20

• X = 25

• X = 15

• X = 5
