Question

a number is subtracted from-13to get-40​

Answer 1

Answer:

-40-(-13)

-40+13

40-13

-27

Answer 2

Let the number which is subtracted from-13 to get -40 be x.

Now , according to the question :-

$\implies - 13 - x = - 40$

Now we will bring -13 from left hand side to right hand side. Therefore it's sign will change from negative to positive.

$\implies - x = - 40 + 13$

$\implies - x = - 27$

Now, we will cancel out negative sign from both the sides.

$\implies x = 27$

Answer :

27 is subtracted from -13 to get -40.

Verification of answer :-

To verify our answer , we will substract 27 from -13. If we get -40 then our answer is correct.

$\implies - 13 - ( 27)$

$\implies - 13 -27$

$\implies - 40$

Therefore when we substracted 27 from -13 , we got -40. Therefore our answer is correct.

Hence verified
