3+√(z-5)=√(z+10)
\n" ); document.write( "---
\n" ); document.write( "Square both sides to get:
\n" ); document.write( "9 + 6sqrt(z-5) + (z-5) = z+10
\n" ); document.write( "---
\n" ); document.write( "Rearrange:
\n" ); document.write( "6sqrt(z-5) = 6
\n" ); document.write( "----
\n" ); document.write( "sqrt(z-5) = 1
\n" ); document.write( "Square both sides:
\n" ); document.write( "z-5 = 1
\n" ); document.write( "z = 6
\n" ); document.write( "-----
\n" ); document.write( "Check the \"answer\":
\n" ); document.write( "3 + sqrt(6-5) = sqrt(6+10)
\n" ); document.write( "3 + 1 = 4
\n" ); document.write( "4 = 4
\n" ); document.write( "---------------
\n" ); document.write( "Therefore: z = 6
