Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Step-by-step explanation:

Let's set Huilan's age to h and Thomas's age to t.

Since Huilan is 13 years younger than Thomas, we can write:

  • h = t - 13

The sum of both their ages is 41, so let's combine the variables h and t together.

  • h + t = 41

We said that h = t - 13, so substitute this value into the equation.

  • (t - 13) + t = 41

Combine like terms.

  • 2t - 13 = 41

Add 13 to both sides of the equation.

  • 2t = 54

Divide both sides of the equation by 2.

  • t = 27

Thomas's age is 27 years old.
