Square root 3x-5 (-) square root 4-7x =0
\n" ); document.write( "-------------
\n" ); document.write( " $\"sqrt%283x-5%29+=+sqrt%284-7x%29\"$
\n" ); document.write( "Square both sides
\n" ); document.write( "3x-5 = 4-7x
\n" ); document.write( "10x = 9
\n" ); document.write( "x = 9/10
\n" ); document.write( "---------------
\n" ); document.write( "Check:
\n" ); document.write( " $\"sqrt%283x-5%29+=+sqrt%284-7x%29\"$
\n" ); document.write( " $\"sqrt%282.7-5%29+=+sqrt%284-6.3%29\"$
\n" ); document.write( " $\"sqrt%28-2.3%29+=+sqrt%28-2.3%29\"$ \n" ); document.write( "
