Answer:

Sum: 27 + -8 = 19

Difference: 27 - -8 = 35

Step-by-step explanation:

The sum of two numbers is 19 and their difference is 35. 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 35. In other words, x minus y equals 35 and can be written as equation B:

x - y = 35

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

x - y = 35

x = 35 + y

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

x + y = 19

35 + y + y = 19

35 + 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 = 27

Summary: The sum of two numbers is 19 and their difference is 35. What are the two numbers? Answer: 27 and -8 as proven here:

Sum: 27 + -8 = 19

Difference: 27 - -8 = 35
