How can I add X distance to the west (or north or east or north) to coordiates?

Question

I want to add X distance to the west (or north or east or north) to coordinates.

I get coordinates like this :

        LocationListener locationListener = new MyLocationListener();                   
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
private class MyLocationListener implements LocationListener {

        @Override
        public void onLocationChanged(Location loc) {

             longitude = loc.getLongitude();
             latitude  = loc.getLatitude();
             altitude  = loc.getAltitude();

        }

        @Override
        public void onProviderDisabled(String provider) {}

        @Override
        public void onProviderEnabled(String provider) {}

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {}
    }

I find set mock location like this:

try { 
                    Location mockLocation = new Location(provider); // a string
                    mockLocation.setLatitude(latitude);  // double 
                    mockLocation.setLongitude(longitude); 
                    mockLocation.setAltitude(altitude);  
                    mockLocation.setTime(System.currentTimeMillis());
                    mockLocation.setAccuracy( Float.parseFloat("20"));
                    mockLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());

                    locationManager_mock.addTestProvider(LocationManager.GPS_PROVIDER, 
                            false, false, false, false, true, true, true,
                            Criteria.POWER_LOW, Criteria.ACCURACY_FINE);

                    locationManager_mock.setTestProviderLocation(provider, mockLocation); 
                } catch (Exception e) { 
                     Toast.makeText(getApplicationContext(), 
                             toastt, Toast.LENGTH_LONG).show();
                }

            }
        });

But I do not want to add 20 meters to west or somewhere?

thanks in advance.

I ve seen that question but I cant understand how can I set location to 20 meters left acn you explain — CompEng, Jul 15 '16 at 19:12
they are not my answer. I want to add 10 meter to the just to the west(this is optional) from my coordinates. — CompEng, Jul 17 '16 at 16:36
That it your answer. Use the equation. Adding distance in GPS location is actually complex, as the longitude depends on the latitude. — Gabe Sechan, Jul 17 '16 at 16:37
but ı do not want to 100 meters around my coordinate. I want to 100 meter to the west or east or north okey — CompEng, Jul 17 '16 at 16:40
And the equations let you do that. If you don't know how to use an algebraic equation then you need to study math. — Gabe Sechan, Jul 17 '16 at 16:41
