2d game sidescroller camera UNITY 5

Hello. I never used 2d and i want to do a sidescroller camera for my characher. How do i do that? only in x. This is what i tried:

using UnityEngine;
using System.Collections;

public class CameraAnchor : MonoBehaviour {

	public Transform player;
	public float distance = 10f;

	// Use this for initialization
	void Start () {

	}
	
	// Update is called once per frame
	void LateUpdate () {
	
		transform.position = player.position + Vector3 (distance, 0, 0);

	}
}

But it give me a error:

Expression denotes a type', where a variable’, value' or method group’ was expected

I hope someone can help me with this. I did try search in internet i keep getting the same error or the same code.

Your line #17 should be:

transform.position = player.position + new Vector3 (distance, 0, 0);

Notice the new keyword before the Vector3(...).
