Sum of two numbers is 95. If one exceeds the other by 15, find the numbers.
Let the smaller number = x.
∴         The other number = x +15.
 According to the condition, we have
               x + [x+15] = 95
                    2x + 15 =95
or                             2x = 95 - 15 = 80
  Dividing both sides by 2, we have
                    x = 80 + 2 = 40
∴
