Question

What are those two remember whose sum is 58 and different is 28 ????

Answer 1

the no. are 43 and 15

Answer 2

Let the numbers be x and y.

Therefore,

x+y = 58................1

x-y = 28
or, x = 28+y.........2

By substituting value of x from 2 and putting it in 1, we get -

x + y = 58

or, (28+y)+y = 58

or, 28+2y = 58

or, 2y = 58-28

or, 2y = 30

or, y = 30/2

or, y = 15

Therefore, one number is 15.

x + y = 58

or , x + 15 = 58

or, x = 58-15

or, x = 43

Answer→ The numbers are 43 and 15.
