Final answer:
The solution to the equation is a = -4.
Step-by-step explanation:
The given equation is 2(4-a) = 16. We can solve this equation to find the value of 'a' that satisfies the equation.
Distribute 2 to the terms inside the parentheses: 8 - 2a = 16. Subtract 8 from both sides: -2a = 8. Divide both sides by -2: a = -4.
Therefore, the solution to the equation is a = -4.
