Using the numbers [12, 25, 87, 5], create an equation that equals 658. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags, discussing how you selected operations and which order the numbers were used in. Once you have the solution and are confident, return the final equation and answer in <answer> </answer> tags, for example <answer> (12 + 5) * 25 - 87 = 658 </answer>.<|im_end|>
