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