What I am trying to achieve:

If I need to shoot say 3 raycasts (C#): 1 from transform.position (blue line), 1 to the left of this by an offset of lets say 2 units (left yellow line), and 1 to the right by the same offset (right yellow line), how can I do this? I imagine it could be something like:

transform.position + publicVariable (and)

transform.position - publicVariable

Here is my script:

using UnityEngine;
using System.Collections;

public class EnemyAI3 : MonoBehaviour {
    public Transform target;
    public int raycastLength = 1;
    public float leftRaycast = 2f;

public float rightRaycast = -2f;

    public bool raycastHitting = false;
    public bool raycastHittingL = false;
    public float turnSpeed = 5;

    private Transform myTransform;

    void Awake() {
       myTransform = transform;
    }

    // Use this for initialization
    void Start () {
       GameObject go = GameObject.FindGameObjectWithTag("Player");
       target = go.transform;
       leftRaycast.x -= 2;
       rightRaycast.x += 2;
    }

    // Update is called once per frame
    void FixedUpdate () {

       //Start Raycast forward
       if(Physics.Raycast(myTransform.position, myTransform.forward, raycastLength)){
         Debug.DrawLine(myTransform.position, myTransform.forward, Color.blue);
         myTransform.Rotate(Vector3.up, -90 * turnSpeed * Time.smoothDeltaTime);
         raycastHitting = true;

       }
       if(!Physics.Raycast(myTransform.position, myTransform.forward, raycastLength)){
         raycastHitting = false;  
       }
       //End Raycast



        //Start Raycast Left
       if(Physics.Raycast(myTransform.position, myTransform.right * leftRaycast, raycastLength)){
         Debug.DrawLine(myTransform.position, myTransform.right * leftRaycast, Color.yellow);
         myTransform.Rotate(Vector3.up, 90 * turnSpeed * Time.smoothDeltaTime);
         raycastHittingL = true;

       }
       if(!Physics.Raycast(myTransform.position, myTransform.right * leftRaycast, raycastLength)){
         raycastHittingL = false; 
       }
       //End Raycast
    }
}

What is the best way to do this?
