Select XElement where the child has a value

Given the following XML:

<platforms>
  <platform>
    <id>1</id>
    <price>2.99</price>
  </platform>
</platforms>

How can I select the platform element as an XElement based on the id child of value 1?

I'm so far away:

XDocument xPlatformXml = new XDocument();
XElement xel = xPlatformXml.Element("platforms").Elements("platform").Where(x => x.Value == "1").SingleOrDefault();

But it looks for the value in the platform element, not the id.

XDocument xPlatformXml = new XDocument();
XElement xel = xPlatformXml.Element("platforms")
                           .Elements("platform")
                           .Where(x => x.Element("id").Value == "1")
                           .SingleOrDefault();

Or by using the conversion XElementto int:

XDocument xPlatformXml = new XDocument();
XElement xel = xPlatformXml.Element("platforms")
                           .Elements("platform")
                           .Where(x => (int)x.Element("id") == 1)
                           .SingleOrDefault();
