Final answer:

The solution to the given equation is x = -23/21.

Step-by-step explanation:

The given equation is (20x + 16) - (- * + 16) = - (x - 18) - 9. To solve this equation, we simplify the expressions on both sides. The expression (- * + 16) represents a multiplication sign placed between two positive numbers, which means the answer will have a positive sign. Simplifying further, we have (20x + 16) + 16 = -x + 18 - 9. Combining like terms, we get 20x + 32 = -x + 9.

Next, we isolate the variable terms on one side by adding x to both sides: 20x + x + 32 = 9. Simplifying, we have 21x + 32 = 9. We then isolate the variable by subtracting 32 from both sides: 21x = -23. Finally, we solve for x by dividing both sides by 21: x = -23/21.
