Question

the sum and difference of two numbers are 20 and10 respectively what are the numbers?​

Answer 1

10 , 20

10+10=20

20-10= 10

Answer 2

Answer:

The numbers are 15 and 5.

Step-by-step explanation:

Let the numbers be x and y

AQ

x+y=20

=> x= 20-y ------ (i)

now putting the value of x from (i)

x-y = 10

=> 20-y = 10+y

=> 20-10 = y+y

=> 10= 2y

=> 10/2 = y

=> 5 = y --------(ii)

Therefore putting the value of y from (ii)

(i) => x = 20-5

=> x = 15

Therefore, x = 15 and y = 5.

Thank you, hope y'all are doing good.
