Let the two number be x and y
the sum of first two numbers is 25
=> x + y = 25 ........eq.. (Ⅰ)
difference is 1
=> x - y = 1 .........eq.. (Ⅱ)
adding equation ( Ⅰ ) and ( Ⅱ )
=> x + x + y - y = 25 + 1
=> 2x = 26
put x = 13 in eq ( Ⅰ ) we get
=> x+y = 25
=> 13 + y = 25
=> y = 25 - 13
=> y = 12
The two numbers are 13 and 12 !
