A collection of stamps consist of 3¢ stamps, 7¢ stamps, and 12 ¢ stamps.
\n" ); document.write( "The number of 3 ¢ stamps is five less than the number of 7 ¢ stamps.
\n" ); document.write( "t = s - 7
\n" ); document.write( "----------------
\n" ); document.write( "The number of 12 ¢ stamps is one-half the number of 7 ¢ stamps.
\n" ); document.write( "w = (1/2)s
\n" ); document.write( "---------------------------
\n" ); document.write( "The total value of all the stamps is $2.73.
\n" ); document.write( "t + s + w = 273
\n" ); document.write( "Find the number of each type of stamp in the collection.
\n" ); document.write( "--------------------
\n" ); document.write( "Substitute for \"t\" and for \"w\" and solve for \"s\"::
\n" ); document.write( "s-7 + s + (1/2)s = 273
\n" ); document.write( "----------------------------
\n" ); document.write( "(5/2)s = 280
\n" ); document.write( "s = 2*56
\n" ); document.write( "s = 112
\n" ); document.write( "----
\n" ); document.write( "t = s-7 = 105
\n" ); document.write( "----
\n" ); document.write( "w + s/2 = 56
\n" ); document.write( "-----------------
