To solve the equation "twice the difference of x and 8 is -18," we first need to determine the difference of x and 8, which is x - 8. Then, we multiply this difference by 2 to get "twice the difference," which becomes 2(x - 8). Setting this equal to -18 gives us the equation 2(x - 8) = -18. Solving for x, we distribute the 2 to get 2x - 16 = -18, then add 16 to both sides to get 2x = -2, and finally divide by 2 to find x = -1.
