Answer:
let first number = X
let second number = y
their sum = 35
X + y = 35 (1st equation)
and their difference = 13
X - Y = 13 ( 2nd equation)
subtract 2nd equation from 1st equation
=
X + y = 35
X - Y = 13
2x = 48
X = 48/2
X = 24.
put the value of X in 1st equation
X + Y = 35
24 + y = 35
y = 35 - 24
Y = 11
