\"John is 3 times as old as Beth\" ___ j = 3b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"The sum of their ages is 36\" ___ j + b = 36 ___ 3j + 3b = 108\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting j for 3b ___ 3j + (j) = 108 ___ 4j = 108
\n" ); document.write( "
\n" );
