\n" ); document.write( "Present age of Bill = x
\n" ); document.write( "Six year ago he was = x-6
\n" ); document.write( "Then
\n" ); document.write( "Bill was 1/4 of his present age\r
\n" ); document.write( "\n" ); document.write( "1/4x=x-6
\n" ); document.write( "x/4=x-6
\n" ); document.write( "x=4(x-6)
\n" ); document.write( "x=4x-24
\n" ); document.write( "x-4x=-24
\n" ); document.write( "-3x=-24
\n" ); document.write( "-3x/-3=-24/-3
\n" ); document.write( "x=8\r
\n" ); document.write( "\n" ); document.write( "Bill is 8 years old \r
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "======
\n" ); document.write( "Bill present age 8 years
