Let's name these two digits as a (tens digit) and b (units digit) and then rephrase the problem statement using a and b.

\n" ); document.write( "The part of the sentence \"three times the tens digit is 2 less than twice the units digits\" translates into:
\n" ); document.write( "3a = 2b - 2
\n" ); document.write( "
Considering that both a and b have to be integer numbers less than 10 and that a will have to be an even number
\n" ); document.write( "(since 2b - 2 is always even and for 3a to be even, a will have to be even),
\n" ); document.write( "the only possible options that will satisfy this equation are: 47 and 24.
\n" ); document.write( "
The second part of the problem statement does not make much sense.
\n" ); document.write( "What exactly is twice the number obtained by reversing the digits?
\n" ); document.write( "In case of 47, twice the number obtained by reversing the digits is 2*74 = 148.
\n" ); document.write( "In case of 24, twice the number obtained by reversing the digits is 2*42 = 84.
\n" ); document.write( "
This is not well formulated question.
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "

\n" );
