The Sum of Two Numbers is 69 and Their Difference is 5

The sum of two numbers is 69 and their difference is 5. 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 69. In other words, x plus y equals 69 and can be written as equation A:

x + y = 69

The difference between x and y is 5. In other words, x minus y equals 5 and can be written as equation B:

x - y = 5

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

x - y = 5
x = 5 + y

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

x + y = 69
5 + y + y = 69
5 + 2y = 69
2y = 64
y = 32

Now we know y is 32. Which means that we can substitute y for 32 in equation A and solve for x:

x + y = 69
x + 32 = 69
X = 37

Summary: The sum of two numbers is 69 and their difference is 5. What are the two numbers? Answer: 37 and 32 as proven here:

Sum: 37 + 32 = 69
Difference: 37 - 32 = 5
