Solve for x: 5x - 15 = 0. What is the value of x?

To solve the equation 5x - 15 = 0, the first step is to isolate the variable x. Start by adding 15 to both sides of the equation, which transforms it into 5x = 15.

Next, to solve for x, you need to divide both sides of the equation by 5. This yields x = 15 / 5.

Carrying out the division gives you x = 3. Therefore, the value of x that satisfies the equation is 3, which corresponds with one of the answer choices provided.

This step-by-step method ensures that the solution is approached logically, leading to the correct answer.
