Question

Find two numbers whose sum is 37 and difference is 9.

Answer 1

Answer:

23 and 14

Step-by-step explanation:

The sum of x and y is 37. In other words, x plus y equals 37 and can be written as equation A:

x + y = 37

The difference between x and y is 9. In other words, x minus y equals 9 and can be written as equation B:

x - y = 9

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

x - y = 9

x = 9 + y

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

x + y = 37

9 + y + y = 37

9 + 2y = 37

2y = 28

y = 14

Now we know y is 14. Which means that we can substitute y for 14 in equation A and solve for x:

x + y = 37

x + 14 = 37

X = 23

Summary: The sum of two numbers is 37 and their difference is 9. What are the two numbers? Answer: 23 and 14 as proven here:

Sum: 23 + 14 = 37

Difference: 23 - 14 = 9

Answer 2

Step-by-step explanation:

So...the two numbers which sum is 37 and differences is 9 is 24 and 15 cause...

• 24 + 15 = 39
• 24 - 15 = 9
