Step by step



Dear,
Who can help me?
I need a step by step solution of the following equation: 
sqrt(3-sqrt(x-1))-sqrt(x-sqrt(2)).

The only result I get is the following: sqrt(x-sqrt(2))=sqrt(3-sqrt(x-1)).

Now, how can i get a right result for x by a step by step solution?
Many many thanks.
Igor
