          sqrt%28x-1%29+=+3



          %28sqrt%28x-1%29%29%5E2 = 3%5E2



                    x - 1 = 9

                        x = 9 + 1

                        x = 10



Checking:



  sqrt%28x-1%29+=+3, x = 10



  sqrt%2810-1%29+=+3



  sqrt%289%29+=+3



         3 = 3 --------------> True



Therefore x = 10
