Solve the equation. \[ \frac{x}{5}-x=8 \] \[ \mathrm{x}= \] (Type an integer or a fraction. Simplify your answer.)

Step 1 ：Multiply every term by 5 to get rid of the fraction: \(x - 5x = 40\)

Step 2 ：Combine like terms on the left side of the equation: \(-4x = 40\)

Step 3 ：Divide both sides of the equation by -4 to solve for x: \(x = -10.0\)

Step 4 ：The solution to the equation is \(\boxed{-10}\)
