Answer:
Question:- The sum of 2 numbers is 11 and their differences is 5.
Añswër:-
Let the 2 numbers be x and y.
ATQ,
x + y = 11
=> x = 11 - y (1)
=> x - y = 5
=> 11 - y - y = 5 ( Equation 1)
=> -2y = 5 - 11
=> -2y = -6
=> y = -2/-6
=> y = 3
so, the first number is 3.
now, putting this on equation 1.
x = 11-3
=> x = 8
so, the second number is 8.
Hence the 2 numbers is 3 and 8.
★ 8 + 3 = 11
★ 8 - 3 = 5
