The Sum of Two Numbers is 59 and Their Difference is 7

The sum of two numbers is 59 and their difference is 7. 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 59. In other words, x plus y equals 59 and can be written as equation A:

x + y = 59

The difference between x and y is 7. In other words, x minus y equals 7 and can be written as equation B:

x - y = 7

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

x - y = 7
x = 7 + y

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

x + y = 59
7 + y + y = 59
7 + 2y = 59
2y = 52
y = 26

Now we know y is 26. Which means that we can substitute y for 26 in equation A and solve for x:

x + y = 59
x + 26 = 59
X = 33

Summary: The sum of two numbers is 59 and their difference is 7. What are the two numbers? Answer: 33 and 26 as proven here:

Sum: 33 + 26 = 59
Difference: 33 - 26 = 7
