You can put this solution on YOUR website! .
There is no solution in integer numbers.
Indeed, in three years Jenny will be still five years older than Marian.
But 90 does not decompose into the product of two integer factors with the difference of 5.
Solving the problem in irrational numbers would be against common sense.
