Hello!
\n" ); document.write( ".
\n" ); document.write( "If Kelly ran x number of races, we can then say Kim ran 2x-4=18.
\n" ); document.write( "So we now solve for x to determine how many races Kelly ran.
\n" ); document.write( ".
\n" ); document.write( "\"2x-4=18\"
\n" ); document.write( "\"2x=18%2B4\"
\n" ); document.write( "\"2x=22\"
\n" ); document.write( "\"x=22%2F2\"
\n" ); document.write( "\"x=11\"
\n" ); document.write( ".
\n" ); document.write( "Since Kelly is x, she ran 11 races.
\n" ); document.write( ".
\n" ); document.write( "Let's check for Kim's number of races.
\n" ); document.write( "\"2x-4=18\"
\n" ); document.write( "\"%282%2A11%29-4=18\"
\n" ); document.write( "\"22-4=18\"
\n" ); document.write( "\"18=18\" ... it checks!
\n" ); document.write( ".
\n" ); document.write( "Done! :)
