Answer 2

Answer:

-25 should be subtracted form 25 to get 50 and -25 should be added to 50 to get 25

Step-by-step explanation:

To Find : What should be subtracted form 25 to get 50 and what should be added to 50 to get 25

Solution:

To Find What should be subtracted form 25 to get 50

Let the number be x

So, $25-x=50$

$25-50=x$

$-25=x$

So, -25 should be subtracted form 25 to get 50

Now to find what should be added to 50 to get 25

Let the number be y

So, $50+y=25$

$y=25-50$

$y=-25$

So, -25 should be added to 50 to get 25
