Let's call the two numbers X and Y. According to the given information, we have:
X + Y = 18 (sum of the two numbers is 18)
X - Y = 2 (difference of the two numbers is 2)
Now, we can solve these two equations simultaneously to find the values of X and Y.
Adding the two equations together:
(X + Y) + (X - Y) = 18 + 2
2X = 20
X = 10
Substitute X = 10 into the first equation:
10 + Y = 18
Y = 8
Therefore, the two numbers are 10 and 8.
the sum of two numbers is 18 and their difference is 2. what are the two numbers?
