Answer:

<u>The</u><u> </u><u>numbers</u><u> </u><u>are</u><u> </u><u>1</u><u>2</u><u> </u><u>and</u><u> </u><u>8</u>

Step-by-step explanation:

let the numbers be x and y :

x + y = 20 -  -  - (a) \\ x - y = 4 -  -  - (b)

add (a) and (b):

2x + 0y = 24 \\ 2x = 24 \\ x = 12

find y:

x + y = 20 \\ 12 + y = 20 \\ y = 20 - 12 \\ y = 8

How can I write a story about the doubles plus 2 fact 5+7=12.??
aksik [14]
One <u>possible story</u> is:

I had 5 apples.  My sister gave me 7, and now I have 12.

Explanation:

We are writing a story for 5+7=12.  This means we need to start with 5 objects and somehow gain 7 more.  In our story, we start with 5 apples and we get 7 more.

The last part is that our total must be 12.  In our story, we end with 12 apples.
