To solve the equation \(0.2x - 2.15 = -8.27\), follow these steps:

  1. Add 2.15 to both sides to isolate the term with \(x\):

    \[ 0.2x - 2.15 + 2.15 = -8.27 + 2.15 \]

    This simplifies to:

    \[ 0.2x = -6.12 \]

  2. Divide both sides by 0.2 to solve for \(x\):

    \[ x = \frac{-6.12}{0.2} \]

    Performing the division:

    \[ x = -30.6 \]

Thus, the solution to the equation is \( \text{-30.6} \).
