I created layout XML file for 2columns-left layout. I need to use two options 2columns-left and 2columns-right in system configuration. When admin selects 2columns-right it should set layout on Right side and vise versa.

How should i proceed?

If you are doing this for a page, I assume you have a controller action for that page.
You can do this in your controller action:

namespace [Namespace]\[Module]\Controller\[Something];

class SomeAction extends \Magento\Framework\App\Action\Action 
    protected $resultPageFactory;
    protected $scopeConfig;
    public function __construct(
       \Magento\Framework\App\Action\Context $context,
       \Magento\Framework\View\Result\PageFactory $resultPageFactory,
       \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    ) {
        $this->resultPageFactory = $resultPageFactory;
        $this->scopeConfig = $scopeConfig;

    public function execute()
         $page = $this->resultPageFactory->create();
         $layout = $this->scopeConfig->getValue(
         if ($layout) {

I haven't tested the code, so watch out for typos.
