The sum of two numbers is 54 and the difference is 18. What are the numbers?
The sum of two numbers is 54 and the difference is 18, x + y = 54 x - y = 18 (where x and y are the two numbers) adding up equations the result is: 2x = 72 x = 36 y = 54 - x = 54 - 36 = 18 The two numbers are 36 and 18 respectively.

The sum of two numbers is 54 and the difference is 18,
x + y = 54
x - y = 18 (where x and y are the two numbers)
adding up equations the result is:
2x = 72
x = 36
y = 54 - x = 54 - 36 = 18
The two numbers are 36 and 18 respectively.
