let hannah had got x sour balls and y lollipops.
\n" ); document.write( "from the question, we have
\n" ); document.write( "x+y=35--------(first)
\n" ); document.write( "2x+5y=100--------(second)
\n" ); document.write( "(100 cents=$1.00)
\n" ); document.write( "from the first equation, we have
\n" ); document.write( "x+y=35
\n" ); document.write( "y=35-x--------(third)
\n" ); document.write( "by substituting the third equation into the second one, we have
\n" ); document.write( "2x+5(35-x)=100
\n" ); document.write( "2x+175-5x=100
\n" ); document.write( "175-3x=100
\n" ); document.write( "175-100=3x
\n" ); document.write( "3x=75
\n" ); document.write( "\"x=25\"
\n" ); document.write( "by substituting x=25 into the third equation, we have
\n" ); document.write( "y=35-25
\n" ); document.write( "\"y=10\"\r
\n" ); document.write( "\n" ); document.write( "checking:
\n" ); document.write( "(first):25+10=35
\n" ); document.write( "(second):2*25+5*10=50+50=100\r
\n" ); document.write( "\n" ); document.write( "Hannah had got 25 sour balls and 10 lollipops.
\n" ); document.write( " \n" ); document.write( "
\n" );
