You can put this solution on YOUR website!
a = age five years from now (ie his future age in 5 years)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So his age right now is a-5 years old\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "His age 17 years ago is (a-5)-17 = a-5-17 = a-22 years old which is choice A
\n" ); document.write( "
\n" );
