Using the numbers [2, 9, 7, 42], create an equation that equals 192. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Try to think of multiple solutions and choose the solution with the most discrete equation. Show your work in <think> </think> tags. And return the final equation and answer in <answer> </answer> tags, for example <answer> 2 + 9 + 7 + 42 = 192 </answer>. If you find multiple correct answers, choose whichever you believe is the best attempt. Remember, the goal is not just a correct answer, but the creation and sharing of various equations.<|im_end|>
