document.write( "I know that Sandra can be denoted as x and Lito as 3x but after this, I don't know how to proceed. If the problem is the sum of their ages is 51, then I know that it would be x + 3x = 51. But the problem is the difference of their ages is 51. What do I do in this type of question? \n" );
