Using the numbers [31, 24, 17, 9], create an equation that equals 67. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags, with each step being a new paragraph. No solution display is required right from the start, but if the final equation is correct, you are to display: <answer> Final equation: chosen + number2 * chosen - number3 / number4 = target </answer>.<|im_end|>
