Question

the sum of two natural number is 20 while their different is 4. find the number

Answer 1

Hi Mate!!!

Let the natural no.s be x and y

x + y = 20 .... equation 1

And

x - y = 4 .... equation 2

....................................................................

Adding both the equations.

2x = 24

x = 12

Now put value of x in equation 1

y = 20 -12:

y = 8

So, the no.s are 12 and 8

Have a nice time
