Call the number of bags of seeds and bird feed, x and y. Then we write
\n" ); document.write( "x + y = 6 and
\n" ); document.write( "5x + 4y = 28
\n" ); document.write( "Now multiply the top equation by 5 and subtract it...we get
\n" ); document.write( "5x + 4y = 28
\n" ); document.write( "-(5x + 5y = 30)
\n" ); document.write( "---------------
\n" ); document.write( "-y = -2
\n" ); document.write( "y = 2 bags of bird feed mix
\n" ); document.write( "x = 4 bags of seeds
\n" ); document.write( "
\n" );
