The Sum of Two Numbers is 14 and Their Difference is 2

The sum of two numbers is 14 and their difference is 2. 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 14. In other words, x plus y equals 14 and can be written as equation A:

x + y = 14

The difference between x and y is 2. In other words, x minus y equals 2 and can be written as equation B:

x - y = 2

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

x - y = 2
x = 2 + y

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

x + y = 14
2 + y + y = 14
2 + 2y = 14
2y = 12
y = 6

Now we know y is 6. Which means that we can substitute y for 6 in equation A and solve for x:

x + y = 14
x + 6 = 14
X = 8

Summary: The sum of two numbers is 14 and their difference is 2. What are the two numbers? Answer: 8 and 6 as proven here:

Sum: 8 + 6 = 14
Difference: 8 - 6 = 2
