Hi there,
\n" ); document.write( "Make country B's area = 'x'
\n" ); document.write( "Country A's area = 873 + x
\n" ); document.write( "Country A + B = 187,973
\n" ); document.write( "(873 + x) + x = 187,973
\n" ); document.write( "873 + x + x = 187,973
\n" ); document.write( "Collect like terms
\n" ); document.write( "x + x = 187,973 - 873
\n" ); document.write( "2x = 187100
\n" ); document.write( "x = 93,550
\n" ); document.write( "Area of land A = 94,423 km
\n" ); document.write( "Area of land B = 93,550 km
\n" ); document.write( "Hope this helps :-)
