The Sum of Two Numbers is 93 and Their Difference is 4

The sum of two numbers is 93 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 93. In other words, x plus y equals 93 and can be written as equation A:

x + y = 93

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 = 93
4 + y + y = 93
4 + 2y = 93
2y = 89
y = 44.5

Now we know y is 44.5. Which means that we can substitute y for 44.5 in equation A and solve for x:

x + y = 93
x + 44.5 = 93
X = 48.5

Summary: The sum of two numbers is 93 and their difference is 4. What are the two numbers? Answer: 48.5 and 44.5 as proven here:

Sum: 48.5 + 44.5 = 93
Difference: 48.5 - 44.5 = 4
