The Sum of Two Numbers is 43 and Their Difference is 5

The sum of two numbers is 43 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 43. In other words, x plus y equals 43 and can be written as equation A:

x + y = 43

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 = 43
5 + y + y = 43
5 + 2y = 43
2y = 38
y = 19

Now we know y is 19. Which means that we can substitute y for 19 in equation A and solve for x:

x + y = 43
x + 19 = 43
X = 24

Summary: The sum of two numbers is 43 and their difference is 5. What are the two numbers? Answer: 24 and 19 as proven here:

Sum: 24 + 19 = 43
Difference: 24 - 19 = 5
