Dual Monitor Set Up

How do I connect my 2014 Macbook Air to two monitors? I have two monitors: an LG and a Samsung monitor. The LG monitor is currently connected via hdmi through a thunderbolt adapter. I can't seem to find a way to connect the Samsung monitor that only has VGA and DVI ports to my laptop. Is there any way to do it without buying a thunderbolt hub or a usb-vga adapter?
