1. The problem asks to find the values of all nine filled-in expressions or equations (assuming a grid or matrix of nine items). 2. Since the user did not provide explicit expressions, I will demonstrate solving a typical set of nine algebraic expressions or equations step-by-step. 3. For each expression, use algebraic rules such as distribution, combining like terms, and solving for variables. 4. Example: Solve $3x + 5 = 20$. 5. Subtract 5 from both sides: $$3x + 5 - 5 = 20 - 5$$ 6. Simplify: $$3x = 15$$ 7. Divide both sides by 3: $$\frac{\cancel{3}x}{\cancel{3}} = \frac{15}{3}$$ 8. Result: $$x = 5$$ 9. Repeat similar steps for each of the nine expressions. Since no specific expressions were provided, please provide the exact nine expressions to solve them accurately.
