You can put this solution on YOUR website!
If there are 100 stamps, then let x = number of one type of stamp (either one will do!!):
\n" ); document.write( "Let x = number of 5 cent stamps
\n" ); document.write( "100-x = number of 2 cent stamps\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".05x = value of the 5 cent stamps
\n" ); document.write( ".02(100-x) = value of the 2 cent stamps\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The value of the stamps is $3.00, so
\n" ); document.write( ".05x + .02(100-x) = 3.00
\n" ); document.write( ".05x + 2.00 - .02x = 3.00
\n" ); document.write( ".03x + 2.00 = 3.00\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 2.00 from each side:\r
\n" ); document.write( "\n" ); document.write( ".03x + 2.00 -2.00= 3.00-2.00
\n" ); document.write( ".03x = 1.00\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by .03:
\n" ); document.write( ".03x = 1.00
\n" ); document.write( "\"%28.03x%29%2F.03+=+1.00%2F.03\"
\n" ); document.write( "\"x+=+100%2F3+\"
\n" ); document.write( "x= 33 1/3 stamps\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This is NOT possible, since the answer did not come out even. You can't have one third of a stamp.\r
