Good to see you have had a good go at this problem!\r
\n" ); document.write( "\n" ); document.write( "Let K = Kathy's age and L=Lisa's age\r
\n" ); document.write( "\n" ); document.write( "\"K+=+2L\"\r
\n" ); document.write( "\n" ); document.write( "\"K%2B3%2BL%2B3+=+42\"\r
\n" ); document.write( "\n" ); document.write( "\"K%2BL%2B6+=+42\"\r
\n" ); document.write( "\n" ); document.write( "Subsitute K/2 in for L:\r
\n" ); document.write( "\n" ); document.write( "\"K%2B%28K%2F2%29%2B6+=42\"
\n" ); document.write( "\"K%2B%28K%2F2%29+=36\"
\n" ); document.write( "\"%282K%2BK%29%2F2+=36\"
\n" ); document.write( "\"3K%2F2+=+36\"
\n" ); document.write( "\"3K+=+72\"
\n" ); document.write( "\"K+=+24\"\r
\n" ); document.write( "\n" ); document.write( "Does that help? Make any sense?
