Solve for $\"b%5B1%5D\"$
\n" ); document.write( " $\"A+=+%281%2F2%29h%28b%5B1%5D%2Bb%5B2%5D%29\"$ Multiply both sides by 2.
\n" ); document.write( " $\"2A+=+h%28b%5B1%5D%2Bb%5B2%5D%29\"$ Divide both sides by h.
\n" ); document.write( " $\"2A%2Fh+=+b%5B1%5D%2Bb%5B2%5D\"$ Finally, subtract $\"b%5B2%5D\"$ from both sides.
\n" ); document.write( " $\"2A%2Fh+-+b%5B2%5D+=+b%5B1%5D\"$
\n" ); document.write( "The answer:
