Using the numbers [13, 55, 27, 7], create an equation that equals 93. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags, to clearly delineate your findings. Finally, return the final equation in <answer> </answer> tags that shows exactly how you arrived at the target number. For example, <answer> (5 + 4) * 9 = 93 </answer>.<|im_end|>
