Answer:
Solution
Given :-
Sum of two number be = 19
Difference be both be = 9
Find :-
These Both Number
Explanation
Let,
First Number be = x
Second Number be = y
Case(1).
(Sum of two number be = 19)
==> x + y = 19 _________(1)
Case(1).
(Difference be both be = 9)
==> x - y = 9 __________(2)
Add equ(1) & equ(2)
==> 2x = 19 + 9
==> 2x = 28
==> x = 28/2
==> x = 14
Keep value of x in equ(1)
==> 14 + y = 19
==> y = 19 - 14
==> y = 5
Hence
First Number be = 14
Second Number be = 5
