√(27-3x)=x-3
------------------
Square both sides to get:
27-3x = x^2-6x+9
x^2 -3x - 18 = 0
(x-6)(x+3) = 0
x = 6 or x = -3
----
Checking in sqrt(27-3x) = x-3
Check x = 6 ?
sqrt(27-18) = 6-3
sqrt(9) = 3
3 = 3
True
----------------
Check x = -3
sqrt((27+9) = -3-3
sqrt(36) = -6
6 = -6
False
-----
Final solution: x = 6
