The difference of two numbers is 18, and their sum is 90. Find the two numbers.
smaller number =
larger number =

The numbers are 54 and 36. Larger number = 54. Smaller number = 36.

Step-by-step explanation:

Step 1:

Let the numbers be x and y. Given their sum = 90 and difference = 18. Form equations out of it.

⇒ x + y = 90 (1)

⇒ x - y = 18   (2)

Subtract eq (2) from eq (1)

⇒ 2x = 108

⇒ x = 54

Step 2:

Find y.

⇒ y = 90 - x = 90 - 54 = 36
