The Sum of Two Numbers is 41 and Their Difference is 1

The sum of two numbers is 41 and their difference is 1. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 41. In other words, x plus y equals 41 and can be written as equation A:

x + y = 41

The difference between x and y is 1. In other words, x minus y equals 1 and can be written as equation B:

x - y = 1

Now solve equation B for x to get the revised equation B:

x - y = 1
x = 1 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 41
1 + y + y = 41
1 + 2y = 41
2y = 40
y = 20

Now we know y is 20. Which means that we can substitute y for 20 in equation A and solve for x:

x + y = 41
x + 20 = 41
X = 21

Summary: The sum of two numbers is 41 and their difference is 1. What are the two numbers? Answer: 21 and 20 as proven here:

Sum: 21 + 20 = 41
Difference: 21 - 20 = 1
