Solution:
To solve for $$x$$ in the equation given in the image, you first need to simplify the equation:\[x + 5 + 6 = 2^3\]Combine the constant terms on the left-hand side:\[x + 11 = 2^3\]Now, calculate $$2^3$$, which is $$2 \times 2 \times 2 = 8$$. Replace $$2^3$$ with 8 in the equation:\[x + 11 = 8\]Subtract 11 from both sides to solve for $$x$$:\[x = 8 - 11\]\[x = -3\]Therefore, $$x = -3$$.
