How to move object on x axis smoothly?

I want to ask how I can smoothly move object on x axis to left and right ? I want to move exactly only on X axis where z and y axis will stay the same as before the movement. I tried with code:

rb.Transform.Translate(Vector3.right * Time.deltatime * 130);

but that teleports the player i want movement to be fast how much i want. I want to only add on x axis for example if the object is on 

0->X
0->Y
0->Z

I want to move to right then x axis need to be = 4,When i want to get left if the object is moved right and its on coordinates (4,0,0) I want to get back to (0,0,0) when press the key to get left. When i want one more field left the coordinates need to be (-4,0,0) I hope someone will get what i want to achieve.

EDIT:

The blue star is player on position , i want to smoothly move to right and left only on x axis where YZ stays the same, on picture is how i want to move, and i want only smoothly movement not teleporting

enter image description here

BLUE IS WHERE THE PLAYER IS AND YELLOW&GREEN STAR IS WHERE PLAYER NEED TO GO WHEN IS GOING TO RIGHT OFC WHEN GOING TO LEFT NEED TO BE ON THE SAME POSITION AGAIN ... Thanks

Try Vector3.Lerp

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    // Transforms to act as start and end markers for the journey.
    public Transform startMarker;
    public Transform endMarker;

    // Movement speed in units/sec.
    public float speed = 1.0F;

    // Time when the movement started.
    private float startTime;

    // Total distance between the markers.
    private float journeyLength;

    void Start()
    {
        // Keep a note of the time the movement started.
        startTime = Time.time;

        // Calculate the journey length.
        journeyLength = Vector3.Distance(startMarker.position, endMarker.position);
    }

    // Follows the target position like with a spring
    void Update()
    {
        // Distance moved = time * speed.
        float distCovered = (Time.time - startTime) * speed;

        // Fraction of journey completed = current distance divided by total distance.
        float fracJourney = distCovered / journeyLength;

        // Set our position as a fraction of the distance between the markers.
        transform.position = Vector3.Lerp(startMarker.position, endMarker.position, fracJourney);
    }
}

Every frame, you could create a new Vector3 with the object original z and y and just update the x according to time logic. Then assign this vector to the object transform. This is the simplest way.
