Question

^O^⊙▽⊙各代表一个数,如果^O^⊙▽⊙-^O^=75那么^O^=多少⊙▽⊙=多少？

Answer 1

由题意，可得：^O^ ⊙▽⊙ = a，^O^ = a + 75，^O^ ⊙ = a + b，⊙▽⊙ = b
将^O^ ⊙▽⊙代入^O^ ⊙ + ⊙▽⊙ = 2(a + b)，得：a + b = 2(a + 75 + b)
化简后得：a = 2b - 150
将a代入^O^ ⊙ + ⊙▽⊙ = a + b，得：2(a + b) = a + b + b
化简后得：a = 2b
将a代入^O^ ⊙▽⊙ - ^O^ = 75，得：b - (a + 75) = 75
化简后得：b - 2b + 150 = 75
解得：b = 75
因此，^O^ = a + 75 = 2b + 75 = 225，⊙▽⊙ = b = 75。
