Bot GPT 4-o mini To solve the equation
\[ -10 = -10(z + 9), \]
let's start by distributing the \(-10\) on the right side:
\[ -10 = -10z - 90. \]
Next, we can add \(90\) to both sides to isolate the term with \(z\):
\[ -10 + 90 = -10z, \]
which simplifies to:
\[ 80 = -10z. \]
Now, divide both sides by \(-10\) to solve for \(z\):
\[ z = \frac{80}{-10} = -8. \]
Thus, the value of \(z\) that is a solution to the equation is
\[ \boxed{-8}. \]
