The sum of two numbers is 56 and the difference is 20 . What are the numbers?

Answer 1

Greetings! Lets solve this shall we ?

Let the sum of two numbers be equal to 56 as x+y=56 and the difference be x-y=20. Now we have a system of linear equations. Now we solve them by the elimination method such that

x+y=56

x-y=20

-----------

2x = 76

x = 38...............................Then we plug 38 into the first equation as

(38) + y = 56

-38 -38

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

y = 18

I hope this helped !
