\n" ); document.write( "x = number of days
\n" ); document.write( "y = amount charged\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Station 1:
\n" ); document.write( "y = x+20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Station 2:
\n" ); document.write( "y = 2x+8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Apply substitution to solve
\n" ); document.write( "2x+8 = x+20
\n" ); document.write( "2x-x = 20-8
\n" ); document.write( "x = 12
\n" ); document.write( "Both stations charge the same amount if 12 days are used.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Confirmation:
\n" ); document.write( "y = x+20 = 12+20 = 32
\n" ); document.write( "y = 2x+8 = 2*12+8 = 24+8 = 32
\n" ); document.write( "Both stations charge $32, so the answer is confirmed.
\n" ); document.write( " \n" ); document.write( "
\n" );
