Answer:
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
