Is the first step in solving different from the first step of solving ? Explain

Question illustration
A
Yes, in the first equation, start by subtracting 8 from both sides to set the equation equal to zero, but in the second equation, start by adding 1 to both sides to isolate the radical.
B
Yes, in the first equation, start by squaring both sides to eliminate the radical, but in the second equation, start by adding 1 to both sides to isolate the radical.
C
No, to solve either equation, square both sides to eliminate all radicals.
D
No, to solve either equation, isolate the radical by adding 1 to both sides.
