Craft an equation using the numbers [22, 33, 44, 55] to equal 77. You can intermix these into a single equation, applying basic arithmetic operations (+, -, *, /) and ensure none of the numbers are reused. Show your work in <think> tags. And submit your final equation and answer in <answer> tags, e.g., <answer> 22 - (33 + 44 / 55) = 0 </answer>.<|im_end|>
