Answer
\( s = 7 \)
Solution
To solve the equation for \( s \):
\[
7s - 7(s + 9) = -9s
\]
**Step 1:** Expand the equation.
\[
7s - 7s - 63 = -9s
\]
**Step 2:** Simplify the left side.
\[
-63 = -9s
\]
**Step 3:** Solve for \( s \) by dividing both sides by \(-9\).
\[
s = \frac{-63}{-9} = 7
\]
\(\boxed{7}\)

Simplify this solution Mind Expander
To solve for \( s \) in the equation \( 7s - 7(s + 9) = -9s \), let's start by distributing the \(-7\): \[ 7s - 7s - 63 = -9s \] This simplifies to: \[ -63 = -9s \] Now, divide both sides by \(-9\): \[ s = \frac{63}{9} \] Simplifying that gives: \[ s = 7 \] So the solution is \( s = 7 \).
