x - y = 2 : Equation 1
2x + 3y = 4 : Equation 2
Multiplying Equation 1 by 3 gives
3x - 3y = 6 : Equation 3
Adding Equation 2 to Equation 3 gives
5x = 10
Dividing both sides by 5 gives
x = 5
Substituting x=5 into Equation 1 gives
5 - y = 2
Therefore y = 3.
Our final answer is therefore x=5 and y=3

Why must you override the hashcode method while overriding the equals method?
Because, if two objects are supposed to be equal as per the equals() method, then the value returned by the hashCode() method must also be the same. This will not be the case if you override only the equals method and this can have some confusing effects when using those objects with hash related collections. So it is always a good idea to override the hashCode() method if you are providing an implementation for the equals method.
