Let x = Number of 20c stamps
\n" ); document.write( "Therefore, 2x = Number of 32c stamps\r
\n" ); document.write( "\n" ); document.write( "20(x) + 32(2x) = 336
\n" ); document.write( "20x + 64x = 336
\n" ); document.write( "84x = 336
\n" ); document.write( "x = 4 (20c stamps)
\n" ); document.write( "x2 = 8 (32c stamps).\r
\n" ); document.write( "\n" ); document.write( "Verify:
\n" ); document.write( "4 x 20 = 80 cents
\n" ); document.write( "8 x 32 = 256 cents
\n" ); document.write( "80+256 = $3.36.\r
