I'm dealing with some TV character's lines that speak in slang, and I don't
understand what is the meaning of this "～てりゃ" in the following sentence:

> 適当にやってりゃいいだろう。

Here the context:

There are three girl in a classroom. The first girl tell to the second one
that she must act more seriously. Next, the third girl say the line
abovementioned, in defense of the second.

I was thinking, may be that "ってりゃ" a simply variation of "ている"? And if it is
so, which is its origin? And, have it a special nuance of meaning?

May you help me to understand? Thks in advance!
