Question

what is the sum 19 and there diffidence is 3

Answer 1

Answer:

8 and 11.

Step-by-step explanation:

if you add 8 and 11 you will get 19 and if you subtract 8 from 11 you will get the difference of 3

Answer 2

Answer:

The sum of two numbers is 19 and their difference is 3. 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 19. In other words, x plus y equals 19 and can be written as equation A:

x + y = 19

The difference between x and y is 3. In other words, x minus y equals 3 and can be written as equation B:

x - y = 3

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

x - y = 3

x = 3 + y

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

x + y = 19

3 + y + y = 19

3 + 2y = 19

2y = 16

y = 8

Now we know y is 8. Which means that we can substitute y for 8 in equation A and solve for x:

x + y = 19

x + 8 = 19

X = 11

Summary: The sum of two numbers is 19 and their difference is 3. What are the two numbers? Answer: 11 and 8 as proven here:

Sum: 11 + 8 = 19

Difference: 11 - 8 = 3
