The Sum of Two Numbers is 26 and Their Difference is 6

The sum of two numbers is 26 and their difference is 6. 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 26. In other words, x plus y equals 26 and can be written as equation A:

x + y = 26

The difference between x and y is 6. In other words, x minus y equals 6 and can be written as equation B:

x - y = 6

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

x - y = 6
x = 6 + y

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

x + y = 26
6 + y + y = 26
6 + 2y = 26
2y = 20
y = 10

Now we know y is 10. Which means that we can substitute y for 10 in equation A and solve for x:

x + y = 26
x + 10 = 26
X = 16

Summary: The sum of two numbers is 26 and their difference is 6. What are the two numbers? Answer: 16 and 10 as proven here:

Sum: 16 + 10 = 26
Difference: 16 - 10 = 6
