The sum of two numbers is 131, and their difference is 37. Find the value of these two numbers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

x + y = 131,     (1)
x - y =  37.     (2)

Every time when you see such a system, add two equations.

Here you will get 

2x = 131 + 37 = 168.

Hence, x = 168%2F2 = 84.

Find yourself the other number.
