<pre>
Let x be your age.


Then your brothers age is (x+5) years, according to the condition.


The sum of your ages is 111 years


    x + (x+5) = 111.


It is the equation the problem asks to write.


Solve it


    2x + 5 = 111

    2x     = 111 - 5

    2x     = 106

     x     = 106/2 = 53.


Your age is 53 years.                        <U>ANSWER</U>


Your brother's age is  53 + 5 = 58 years.    <U>ANSWER</U>
