What is the solution to the equation 3x - 9 = 0?

To solve the equation (3x - 9 = 0), the first step is to isolate the variable (x). Begin by adding 9 to both sides of the equation:

[3x - 9 + 9 = 0 + 9] This simplifies to:

[3x = 9]

Next, to solve for (x), divide both sides of the equation by 3:

[\frac{3x}{3} = \frac{9}{3}] This simplifies further to:

[x = 3]

Thus, the solution to the equation is (x = 3).

This solution indicates that when substituting (x) with 3 back into the original equation, it satisfies the equation perfectly:

[3(3) - 9 = 9 - 9 = 0]

Verifying the solution is an essential step in confirming that it meets the requirements of the equation, which it does. Therefore, the correct answer is indeed (x = 3).
