Knowing how to read your camera's light meter and how to compensate for exposure are important photography concepts you should understand. Not only will it help you get your exposure correct in-camera, but it will ALSO help you achieve more advanced lighting techniques, such as backlighting.
There are several ways to find the exposure meter on your camera. Here is the meter on a Canon 5d:
The meter is denoted by a +/- button on Nikon, and can be accessed through the interface on the camera's LCD screen. You will also see the exposure meter when you look through your camera's viewfinder.
In the image above, notice that the scale reads -2, 1, 0, 1, +2. Each number represents a full stop in exposure on either your shutter speed or aperture, and the small dots in between each number represent a 1/3 stop.
For example, let's say you have your aperture set to f/3.5. If you move up to the next f/stop, which is f/4 on your lens (and the first dot on the right in your exposure meter), you have changed your exposure 1/3 of a stop.
Now, if you change your exposure from f/3.5 to f/5, you have changed your exposure 1 full stop, which is denoted by the 1 on your meter.
If you change from f/3.5 to f/7.1, you have increased 2 stops, which is denoted by the +2 on your meter.
You don't need to be too concerned with the technical jargon here, just know that moving to the right on your meter will make your image darker, and moving to the left will make it brighter.
Here is a visual representation of "stops" on your exposure meter:
With a backlit image, your camera is going to be metering off of the brightest light source which is going to be the light coming from behind your subject. Since that light is very bright, your camera is going to tell you to move your exposure meter dial to the right (to make the image darker), compensating for the bright light from behind your subject.
Instead, you want to move the dial to the left, to make the image brighter, so that your subject will be well-lit (see images below):
