To solve the equation 0.2x - 2.15 = -8.27, first add 2.15 to both sides of the equation to isolate the x term:
0.2x - 2.15 + 2.15 = -8.27 + 2.15
0.2x = -6.12
Then, divide both sides by 0.2 to solve for x:
x = -6.12 / 0.2
x = -30.6
Therefore, the solution to the equation is x = -30.6, which is answer choice D.
