2C+3S=20.00
\n" ); document.write( "1C+2C=11.25; multiply the second by -2
\n" ); document.write( "-2C-4S=-22.50; add the first and this to eliminate the carrots
\n" ); document.write( "-S=-2.50
\n" ); document.write( "Spinach is $2.50
\n" ); document.write( "2C are $12.50 in first equation, so C=$6.25
\n" ); document.write( "Substitute in second
\n" ); document.write( "$6.25+$5.00=$11.25 so it checks.
