Alter variables in other Game Objects

I have a script to reference one of several arrays and apply the values to a number of variables in a number of Game Objects. I need to know how to reference and change variables from other Game Objects.

 using UnityEngine;
 using System.Collections;
 
 public class MathVariables : MonoBehaviour {
     string[] Eq1 = {"3","x","2","8","3","x","6","","","","","","subtract","2","divide","3","","3x+2=8","3x=6","x=3"};
     public GameObject LeftText;
     public GameObject RightText;
     public GameObject TopText;
     public GameObject BottomText;
 
     // Use this for initialization
     void Start () {
         newEquation();
     }
     
     // Update is called once per frame
     void Update () {
 
         }
 
 
     void newEquation () {
         LeftText.Ringvariable = Eq1[0];
         RightText.Ringvariable = Eq1[1];
         TopText.Ringvariable = Eq1[2];
         BottomText.Ringvariable = Eq1[3];
     }
 }
