The Sum of Two Numbers is 66 and Their Difference is 2

The sum of two numbers is 66 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 66. In other words, x plus y equals 66 and can be written as equation A:

x + y = 66

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 = 66
2 + y + y = 66
2 + 2y = 66
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 = 66
x + 32 = 66
X = 34

Summary: The sum of two numbers is 66 and their difference is 2. What are the two numbers? Answer: 34 and 32 as proven here:

Sum: 34 + 32 = 66
Difference: 34 - 32 = 2
