Question

sum of two numbers is 42 and their differences is 8 find the numbers?​

Answer 1

Answer:

25 and 17

Step-by-step explanation:

Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 42. In other words, x plus y equals 42 and can be written as equation A:

x + y = 42

The difference between x and y is 8. In other words, x minus y equals 8 and can be written as equation B:

x - y = 8

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

x - y = 8

x = 8 + y

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

x + y = 42

8 + y + y = 42

8 + 2y = 42

2y = 34

y = 17

Now we know y is 17. Which means that we can substitute y for 17 in equation A and solve for x:

x + y = 42

x + 17 = 42

X = 25

Summary: The sum of two numbers is 42 and their difference is 8. What are the two numbers? Answer: 25 and 17 as proven here:

Sum: 25 + 17 = 42

Difference: 25 - 17 = 8
