Welcome to Android Central! Which tablet? Swipe down the notification panel and tap the settings gear icon. Then look for the Language option -- if each menu item has an icon associated with it, look for either the globe icon or the letter "A" icon, and select that. The System Language menu should be the first item in that list.
