Solve for x: 3x = 15

To solve the equation 3x = 15, we need to isolate x on one side of the equation. We can do this by dividing both sides of the equation by 3.

Here’s how it works step by step:

1. Start with the original equation: 3x = 15.
2. Divide both sides by 3: x = 15 / 3.
3. Calculate the right side: x = 5.

So, the solution to the equation is x = 5.
