✔ 最佳答案
(h+9) / 9 = 5/6 - 1/2(h+9) = 45/6 - 9/2 兩方X9去分母
(h+9) = 45/6 - 27/6 通分
h + 9 = 18/6
h + 9 = 3
h = 3-9
h = - 6

解二 :
(h+9) / 9 = 5/6 - 1/2
(h+9) / 9 = 5/6 - 3/6 先通分
(h+9) / 9 = 2/6
(h+9) / 9 = 1/3
3(h+9) = 1*9 分子分母交差相乘
3h + 27 = 9
3h = - 18
h = - 18/3
h = - 6

1/9(h+9) =5/6-1/2
1/9(h+9) =5/6-3/6←先計算(通分)
1/9(h+9) =2/6←(約簡)1/3
(h+9) =1/3乘9/1←跳步(1/3除1/9)←再約簡約成3
h = 3-9
h = -6
1/9(h+9) =5/6-3/6←先計算(通分)
1/9(h+9) =2/6←(約簡)1/3
(h+9) =1/3乘9/1←跳步(1/3除1/9)←再約簡約成3
h = 3-9
h = -6
