Question

A) Find two numbers whose sum and difference are 25 and 5 respectively.

Answer 1

Answer:

The two numbers can be 15 and 10

15+10 =25

15-10 =5

Answer 2

Step-by-step explanation:

1st number- x

2nd number - y

x+y= 25_______eq(1)

x-y= 5_________eq(2)

difference eq. (1)& (2)

(x+y)-(x-y)= 25-5

x+y-x+y= 20

2y= 20

y=20/2

y= 10

put value of y in eq. (1)

x+y= 25

x+10=25

x=25-10

x=15

x=15 ,, y=10
