\n" ); document.write( "17 . . . . . . .17 . . . . . . . .63. . . . . . . . . . .1071
\n" ); document.write( "set the third column equal to get
\n" ); document.write( " $\"29p+%2B+945+-+15p+=+1071\"$
\n" ); document.write( "combine like terms to get
\n" ); document.write( " $\"14p+%2B+945+=+1071\"$
\n" ); document.write( "subtract 945 to get
\n" ); document.write( " $\"14p+=+126\"$
\n" ); document.write( "p = 9 pounds @ 29 %
