Checking the description very carefully: A's present age is, means A=;
\n" ); document.write( "4 years more than B's age AFTER 6 years, means 4+B+6;
\n" ); document.write( "That transcribes into \"A=4%2B%28B%2B6%29\". This becomes one of the equations for the system.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Present age sum becomes the other equation for the system, plainly describing \"A%2BB=70\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here is the system:
\n" ); document.write( "\"system%28A=4%2B%28B%2B6%29%2CA%2BB=70%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The steps:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28A=B%2B10%2CA%2BB=70%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28B%2B10%29%2BB=70\"
\n" ); document.write( "\"2B%2B10=70\"
\n" ); document.write( "\"B%2B5=35\"
\n" ); document.write( "\"highlight%28highlight%28B=30%29%29\"------THIS IS THE VALUE FOR B.
\n" ); document.write( "
\n" );
