x + y = 4000; therefore, x = 4000 - y
\n" ); document.write( ".07x + .015y = 225
\n" ); document.write( "...
\n" ); document.write( "substitute
\n" ); document.write( ".07(4000-y) + .015y = 225
\n" ); document.write( "280 - .07y + .015y = 225
\n" ); document.write( "-.055y = 225 - 280
\n" ); document.write( "-.055y = -55
\n" ); document.write( "\"highlight_green%28y+=+1000%29\" at 1.5%
\n" ); document.write( "x = 4000 - 1000 = \"highlight_green%28x+=+3000%29\" at 7%
