the age of a crocodile 13 years ago was 1/3 of its age 7 years from now.
\n" ); document.write( " How old is the crocodile at present?
\n" ); document.write( ":
\n" ); document.write( "The equation for this:
\n" ); document.write( "x - 13 = \"1%2F3\"(x+7)
\n" ); document.write( "multiply both sides by 3
\n" ); document.write( "3(x-13) = x + 7
\n" ); document.write( "3x - 39 = x + 7
\n" ); document.write( "3x - x = 7 + 39
\n" ); document.write( "2x = 46
\n" ); document.write( "x = 46/2
\n" ); document.write( "x = 23 yrs is the present age \n" ); document.write( "
\n" );
