To solve the equation \(-\frac{x}{5} - 3 = 1 + \frac{x}{5}\), we first eliminate the fractions by multiplying the entire equation by 5. This gives us: \[ -5 \cdot \frac{x}{5} - 5 \cdot 3 = 5 \cdot 1 + 5 \cdot \frac{x}{5} \] Which simplifies to: \[ -x - 15 = 5 + x \] Next, we can rearrange the equation by adding \(x\) to both sides and adding 15 to both sides: \[ -x + x - 15 + 15 = 5 + x + 15 \] This results in: \[ 0 = x + 20 \] Now we can isolate \(x\) by subtracting 20 from both sides: \[ x = -20 \] Thus, the solution to the equation is: \[ \boxed{-20} \]
