Let the two different sized boxes be represented by x and y. x is the larger box, y the smaller.
\n" ); document.write( "You are told
\n" ); document.write( " $\"x+%2B+y+=+28\"$
\n" ); document.write( "so $\"x+=+28+-+y\"$
\n" ); document.write( " $\"9.5x+%2B+7.5y+=+234\"$
\n" ); document.write( " $\"9.5%2828-y%29+%2B+7.5y+=+234\"$
\n" ); document.write( " $\"266+-+9.5y+%2B+7.5y+=+234\"$
\n" ); document.write( " $\"-2y+=+-32\"$
\n" ); document.write( " $\"y+=+16\"$
\n" ); document.write( "They bought 16 smaller boxes. To total 28 boxes, they must have 12 larger ones. \n" ); document.write( "
