Answer:
Let the two numbers be x and y. Both x and y are variables.
The sum of two numbers is 9 ,it can be written as x+y=9 --------(1)
and, their difference is 5 ,it can be written as x-y=5 ----------(2)
From (1) and (2), solve the equations simultaneously :-
x+y=9
x-y=5
______________________________
2x =14
=>x = 7 ----(3)
Putting the value of x in the equation (1),
=>7+y = 9
=>y = 2.
The value of x and y are 7 and 2.
