Since the difference of the two numbers is 1, we take 1 away from their sum, so that both the numbers are the same: 19 - 1 = 18
Since both of the numbers are the same now, we divide the numbe by 2 to get the smaller number: 18 ÷ 2 = 9
The difference between the two numbers is 1, so we add 1 to the smaller number to find the bigger number: 9 + 1 = 10
