Answer 1

Let us assume one number = x
and Let us assume the other number to be = y
Then
 x + y = 170
and
x - y = 26
Adding the two equations, we get
2x = 196
x = 98
Putting the value of x in the first equation, we get
x + y = 170
98 + y = 170
y = 170 - 98
  = 72
The solution can be written as (98, 72). I hope the procedure is clear enough for you to understand.
