0.1*0.95 + 0.9x = 0.8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.095 + 0.9x = 0.8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.9x = 0.8-0.095\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.9x = 0.705\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 0.705/0.9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 0.78333333333333\r
