Question

Two numbers have a sum of 822 and a difference of 258. What are the two numbers?

Answer 1

540 and 282

Explanation:

x + y = 822

x - y = 258

Combine the equations

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

2x = 1080

x = 540

Plug in x to the first equation

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

y + 540 = 822

- 540 -540

y = 282

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

x = 540 and y = 282
