✔ 最佳答案
5y/6 = (1/6)y - 1 《 《 《 先乘除後加減5y/6 = y/6 - 6/6 《 《 《 同分母可省去不計
5y = y - 6
4y = - 6
y = - (6/4)
y = - 1.5

5y/6 = 1/6 y -1
(5y/6) X 6 = (1/6 y -1) X6
5y = y - 6
4y = -6
y = - 1.5
2008-01-16 15:53:41 補充：
還 是5y/6 = 1/6 (y-1)5y/6 X 6 = 1/6(y-1) X 65y = y-14y = -1y = -1/4
(5y/6) X 6 = (1/6 y -1) X6
5y = y - 6
4y = -6
y = - 1.5
2008-01-16 15:53:41 補充：
還 是5y/6 = 1/6 (y-1)5y/6 X 6 = 1/6(y-1) X 65y = y-14y = -1y = -1/4
2008-01-16 11:42 pm
5y/6 = (1/6)(y-1)
5y = y-1
5y - y = -1
4y = -1
y = -1/4 = -0.25
5y = y-1
5y - y = -1
4y = -1
y = -1/4 = -0.25
