Using the numbers [33, 44, 39, 24], create an equation that equals 87. You can only use each number once using basic arithmetic operations (+, -, *, /). Break down each step to show your thought process in <think> </think> tags, and present your final equation and answer in <answer> </answer> tags. For example, if your final result is (a + b) * c - d = x, you would write your step-by-step process and the solution like: <think>First, we subtract 24 from 39: 39 - 24 = 15. Next, we multiply this result by 44: 15 * 44 = 660. Then, we add 33 to the previous result: 660 + 33 = 693. Finally, we subtract 87 from this last result: 693 - 87 = 606. This is incorrect; we need to work backward. We reversed the steps and instead done: 44 * 33 + 24 - 39. Our final equation is : <answer> 44 * 33 + 24 - 39 = 1452 - 39 = 1413 - 87 = 1326. </answer></think>. Make sure your answer is balanced and logical.<|im_end|>
