# One number is 4 more than another, and their sum is 60. What is the smaller number?

In algebra, the problem is expressed as a mathematical expression using variables and constants called an equation. To find the unknown numbers we will use an algebraic expression with variables and constants.

## Answer: The smaller number is 28.

Let's find the smaller number.

**Explanation:**

To find the numbers we will have linear equation with one variable.

Let the smaller number be 'x' and the larger number be x + 4

⇒ x + (x + 4) = 60

⇒ 2x + 4 = 60

By subtracting both sides by 4, we get

⇒ 2x = 56

By dividing both sides by 2, we get

⇒ x = 56 / 2

⇒ x = 28
