To solve for \( y \) given \( x = 5 \) in the equation:
\[ -9x - 7y = 11 \]
we can substitute \( x = 5 \) into the equation:
\[ -9(5) - 7y = 11 \]
Calculating \( -9 \times 5 \):
\[ -45 - 7y = 11 \]
Next, we will isolate the \( y \) term by adding 45 to both sides:
\[ -7y = 11 + 45 \]
\[ -7y = 56 \]
Now, divide both sides by -7:
\[ y = \frac{56}{-7} \]
\[ y = -8 \]
So when \( x = 5 \), \( y = -8 \). Therefore, the solution in the form \((x, y)\) is:
\[ (5, -8) \]
