Let $\"x\"$ = number of graphing calculators bought
\n" ); document.write( " $\"49+-+x\"$ = number of scientific calculators bought
\n" ); document.write( " $\"8%2A%2849+-+x%29+%2B+55x+=+1755\"$
\n" ); document.write( " $\"392+-+8x+%2B+55x+=+1755\"$
\n" ); document.write( " $\"47x+=+1363\"$
\n" ); document.write( " $\"x+=+29\"$
\n" ); document.write( " $\"49+-+x+=+20\"$
\n" ); document.write( "20 scientific and 29 graphing were bought
\n" ); document.write( "check:
