Let's solve the equations step by step.

Equation 1: \( x - 9 = -2 \)

To solve for \( x \), add 9 to both sides:

\[ x = -2 + 9 \] \[ x = 7 \]

Equation 2: \( x^2 y = 196 \)

Now, we can substitute the value of \( x \) we found into the second equation:

\[ 7^2 y = 196 \]

Calculate \( 7^2 \):

\[ 49y = 196 \]

Next, divide both sides by 49 to solve for \( y \):

\[ y = \frac{196}{49} \] \[ y = 4 \]

Solution:

So the solutions are:

\[ x = 7 \] \[ y = 4 \]
