Question

find two numbers whose sum is 26 and difference is 4

​

Answer 1

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 26. In other words, x plus y equals 26 and can be written as equation A:

x + y = 26

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 = 26

4 + y + y = 26

4 + 2y = 26

2y = 22

y = 11

Now we know y is 11. Which means that we can substitute y for 11 in equation A and solve for x:

x + y = 26

x + 11 = 26

X = 15

Summary: The sum of two numbers is 26 and their difference is 4. What are the two numbers? Answer: 15 and 11 as proven here:

Sum: 15 + 11 = 26

Difference: 15 - 11 = 4
