Ann is 11 years highlight%28old%29. Her Aunt, Kate turned 47 today. After how many years will Kate be 3 times as old as Ann
~~~~~~~~~~~~~~~~~ 

Let it will happen in x years


    3*(11+x) = 47 + x


Simplify and find x

    33 + 3x = 47 + x

    3x - x = 47 - 33

       2x  =    14

        x  =    14/2 = 7.


ANSWER.  In 7 years.
