Solve for Y:
\n" ); document.write( " $\"sqrt%287Y%2B4%29+=+sqrt%28Y-2%29\"$ Square both sides.
\n" ); document.write( " $\"7Y%2B4+=+Y-2\"$ Subtract Y from both sides.
\n" ); document.write( " $\"6Y%2B4+=+-2\"$ Subtract 4 from both sides.
\n" ); document.write( " $\"6Y+=+-6\"$ Divide both sides by 6.
\n" ); document.write( " $\"Y+=+-1\"$ Check:
\n" ); document.write( " $\"sqrt%287Y%2B4%29+=+sqrt%28Y-2%29\"$ Substitute Y = -1.
\n" ); document.write( " $\"sqrt%287%28-1%29%2B4%29+=+sqrt%28-1-2%29\"$ Simplify.
\n" ); document.write( " $\"sqrt%28-3%29+=+sqrt%28-3%29\"$ \n" ); document.write( "

\n" );
