Question

The sum of two integers is 42, and their difference is 14. Find the integers.

Answer 1

21, 28

Step-by-step explanation: 21+21=42-28=14

Answer 2

x+y = 42

x-y =14

add the two equations

x+y = 42

x-y =14

---------------------

2x = 56

divide by 2

x = 28

x+y =42

28+y = 42

subtract 28

y = 14

The two numbers are 14 and 28
