Question

find two numbers whose sum is 28 and whose difference is 20.

Answer 1

24 + 4 = 28

24 - 4 = 20

:)

Answer 2

I can't really explain how I got the answer, but that is what I got

Answer 3

I think I just found the number in the middle of 20 and 28, and then subtracted that number from 28 to get 4.

Take a look here.

find two numbers whose sum is 100 and whose difference is 50
Number in the middle of 50 and 100 is 75

100 - 75 = 25

Now we have
75 + 25 = 100
75 - 25 = 50

Answer 4

I don't know the proper way to solve this, ahaha

Answer 5

yay chick

Answer 6

\(a+b = 28\) and \(a-b=20\)

So add them together:

\(a+b+a-b = 2a =48\\~\\a=24\)

So \(a+b \to 24+b = 28\)
\(b = 28-24 = 4\)

\(\boxed{a=24,~b=4}\)

Answer 7

That's how you can get answer.

Answer 8

Ah okay :)
