The sum of two numbers is 66. The smaller number is 12 less than the larger number. What are the numbers

The two numbers are 39 and 27.

Step-by-step explanation:

To find these numbers, set the first number equal to x. Then the second number can be described as x - 12. Using these two terms, you can add them together and set equal to 66.

x + x - 12 = 66

2x - 12 = 66

2x = 78

x = 39

Given this as the first number, put into the second equation to find the next.

x - 12

(39) - 12

27
