Solve for \( s \). \( 0.8+s=9(0.2 s+0.8) \) \( s=\square \) Submit

To solve for \( s \) in the equation: \[ 0.8 + s = 9(0.2s + 0.8) \] **Step 1:** Expand the right-hand side. \[ 0.8 + s = 9 \times 0.2s + 9 \times 0.8 \] \[ 0.8 + s = 1.8s + 7.2 \] **Step 2:** Move all terms involving \( s \) to one side and constant terms to the other side. \[ 0.8 = 1.8s + 7.2 - s \] \[ 0.8 = 0.8s + 7.2 \] **Step 3:** Subtract 7.2 from both sides to isolate the terms with \( s \). \[ 0.8 - 7.2 = 0.8s \] \[ -6.4 = 0.8s \] **Step 4:** Divide both sides by 0.8 to solve for \( s \). \[ s = \frac{-6.4}{0.8} \] \[ s = -8 \] **Solution:** \[ s = -8 \]
