The given equation is $9x - 2 = 6$.

To solve this, we need to isolate $x$. The first step should be to add 2 to both sides of the equation, so that we remove the -2 from the left-hand side.

• $9x - 2 + 2 = 6 + 2$
• This simplifies to $9x = 8$.

Thus, the correct answer is:

Add 2 to both sides of the equation.
