Solve the following math problem efficiently and clearly:

- For simple problems (2 steps or fewer):
Provide a concise solution with minimal explanation.

- For complex problems (3 steps or more):
Use this step-by-step format:

## Step 1: [Concise description]
[Brief explanation and calculations]

## Step 2: [Concise description]
[Brief explanation and calculations]

...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: In triangle $ABC,$ $a = 7,$ $b = 9,$ and $c = 4.$  Let $I$ be the incenter.

[asy]
unitsize(0.8 cm);

pair A, B, C, D, E, F, I;

B = (0,0);
C = (7,0);
A = intersectionpoint(arc(B,4,0,180),arc(C,9,0,180));
I = incenter(A,B,C);

draw(A--B--C--cycle);
draw(incircle(A,B,C));

label("$A$", A, N);
label("$B$", B, SW);
label("$C$", C, SE);
dot("$I$", I, NE);
[/asy]

Then
\[\overrightarrow{I} = x \overrightarrow{A} + y \overrightarrow{B} + z \overrightarrow{C},\]where $x,$ $y,$ and $z$ are constants such that $x + y + z = 1.$  Enter the ordered triple $(x,y,z).$
