In a parallelogram adjacent angles are supplementary. From above we have
\n" ); document.write( "(i) $\"3x+%2B++2y+%2B+7+=+180\"$
\n" ); document.write( "(ii) $\"2y+%2B+7+%2B+63+=+180\"$
\n" ); document.write( "we can solve for y in (ii) as
\n" ); document.write( "(iii) $\"2y+%2B+70+=+180\"$
\n" ); document.write( "then
\n" ); document.write( "(iv) $\"2y+=+110\"$
\n" ); document.write( "dividing, we get
\n" ); document.write( "(v) $\"y+=+55\"$
\n" ); document.write( "Now we can solve for x in (i) as
\n" ); document.write( "(vi) $\"3x+%2B+2%2855%29+%2B+7++=+180\"$
\n" ); document.write( "combine like terms to get
\n" ); document.write( "(vii) $\"3x+%2B+117++=180\"$
\n" ); document.write( "subtract to get
\n" ); document.write( "(viii) $\"3x+=+63\"$
\n" ); document.write( "and divide to get
\n" ); document.write( "(ix) $\"x+=+21\"$ \n" ); document.write( "

\n" );
