Let \"+s+\" = number of stamps he has
\n" ); document.write( "Let \"+c+\" = number of coins he has
\n" ); document.write( "given:
\n" ); document.write( "(1) \"+c+=+3%2A%28s%2F2%29+\"
\n" ); document.write( "(2) \"+c+%2B+s+=+51+\"
\n" ); document.write( "-----------------
\n" ); document.write( "Substitute (1) into (2)
\n" ); document.write( "(2) \"+3%2A%28s%2F2%29+%2B+s+=+51+\"
\n" ); document.write( "Multiply both sides by \"+2+\"
\n" ); document.write( "(2) \"+3s+%2B+2s+=+102+\"
\n" ); document.write( "(2) \"+5s+=+102+\"
\n" ); document.write( "----------------
\n" ); document.write( "This doesn't work out to a whole number
\n" ); document.write( "of stamps. I suspect that the problem should read:
\n" ); document.write( "The number of coins he has is 3 more than half the number of stamps.
\n" ); document.write( "and not
\n" ); document.write( "The number of coins he has is 3 TIMES more than half the number of stamps.
\n" ); document.write( "If that is so,
\n" ); document.write( "(1) \"+c+=+s%2F2+%2B+3+\"
\n" ); document.write( "(2) \"+c+%2B+s+=+51+\"
\n" ); document.write( "Substitute (1) into (2)
\n" ); document.write( "(2) \"+s%2F2+%2B+3+%2B+s+=+51+\"
\n" ); document.write( "(2) \"+s+%2B+s%2F2+=+48+\"
\n" ); document.write( "(2) \"+2s+%2B+s+=+96+\"
\n" ); document.write( "(2) \"+3s+=+96+\"
\n" ); document.write( "(2) \"+s+=+32+\"
\n" ); document.write( "and
\n" ); document.write( "(2) \"+c+%2B+s+=+51+\"
\n" ); document.write( "(2) \"+c+%2B+32+=+51+\"
\n" ); document.write( "(2) \"+c+=+19+\"
\n" ); document.write( "He has 19 coins and 32 stamps\r
