The Sum of Two Numbers is 33 and Their Difference is 4

The sum of two numbers is 33 and their difference is 4. 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 33. In other words, x plus y equals 33 and can be written as equation A:

x + y = 33

The difference between x and y is 4. In other words, x minus y equals 4 and can be written as equation B:

x - y = 4

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

x - y = 4
x = 4 + y

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

x + y = 33
4 + y + y = 33
4 + 2y = 33
2y = 29
y = 14.5

Now we know y is 14.5. Which means that we can substitute y for 14.5 in equation A and solve for x:

x + y = 33
x + 14.5 = 33
X = 18.5

Summary: The sum of two numbers is 33 and their difference is 4. What are the two numbers? Answer: 18.5 and 14.5 as proven here:

Sum: 18.5 + 14.5 = 33
Difference: 18.5 - 14.5 = 4
