a) 5/11 + 6/11x = 1 6/11x = 1 – 5/11 6/11x = 6/11 x = 6/11 : 6/11 x = 1 Vậy x = 1 b) 5/12 – x + 5/18 = (-1)/18 5/12 – x = (-1)/18 – 5/18 5/12 – x = (-1)/3 x = 5/12 – (-1)/3 x = 3/4 Vậy x = 3/4 c) 2x – 1/2 = 2/3 2x = 2/3 + 1/2 2x = 7/6 x = 7/6 : 2 x = 7/12 Vậy x = 7/12 d) (-2)/3 : x + 5/8 = (-7)/12 (-2)/3 : x = (-7)/12 – 5/8 (-2)/3 : x = (-29)/24 x = (-2)/3 : (-29)/24 x = 16/29 Vậy x = 16/29 Halary08 Trả lời
