Let the two numbers be a and b
According to the question,
a + b = 17 — equation 1
a - b = 1 — equation 2
On adding equation 1 and 2, we get,
(a+b) + (a-b) = 17 + 1
a + a + b - b = 18
2a = 18
a = 9
Now, putting a=9 in equation 1, we get
a + b = 17
(9) + b = 17
b = 17-9
b = 8
Thus, the two numbers are 9 and 8
