The Sum of Two Numbers is 63 and Their Difference is 1

The sum of two numbers is 63 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 63. In other words, x plus y equals 63 and can be written as equation A:

x + y = 63

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 = 63
1 + y + y = 63
1 + 2y = 63
2y = 62
y = 31

Now we know y is 31. Which means that we can substitute y for 31 in equation A and solve for x:

x + y = 63
x + 31 = 63
X = 32

Summary: The sum of two numbers is 63 and their difference is 1. What are the two numbers? Answer: 32 and 31 as proven here:

Sum: 32 + 31 = 63
Difference: 32 - 31 = 1
