Using the numbers [10, 50, 30, 5], create an equation that equals 98. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Show your work in <think> </think> tags. And return the final equation and answer in <answer> </answer> tags, for example <answer> Solution: (50 - 30) * 5 = 10 * 5 = 50 - 10 = 50 - 10 = 40 * 5 = 200 - 100 = 90 * 5 = 450 - 100 = 350 - 100 = 250 * 5 = 1250 - 460 = 789</answer>. <|im_end|>
