transform:translateX()

                
                        /* <length-percentage> values */
transform: translateX(200px);
transform: translateX(50%);
                    
                

transform.Translate unity

                        
                                transform.Translate(1 ,1 ,1); //where coordinates are x, y and z respectively

//Similarly you can also use:
int speed; //variable
transform.Translate(Vector3.forward * Time.deltaTime * speed); //for moving along z axis
