Ok first lets find the answer .... on our own 

So we have an equation y=x+2

The first step in finding our inverse is to replace x and y:
x=y+2

The next step is to isolate y and set up our equation as y= .....
Its pretty simple. 
Can you tell me what our equation would look like once we isolated y?
