Answer:
9 and 18
Explanation:
Let the unknown number be x
According to the question
(x-9) + x = 27
Solution:
(x-9) + x = 27
x-9+x = 27
x+x = 27+9
2x = 36
x = 36/2
x = 18
Now, let's find the another number by applying the value of x
(18-9) + 18 = 27
9 + 18 = 27
27 = 27
[Therefore, the first number is 9 and the second number is 18.]
