Giúp mình với ạ:((
Bài 1: Tìm x, biết:
a) 390 - (x -20) = 169 : (-13)
b) ( x - 140) : 5 = \(3^{3} - 2^{3}\) . 3
c) 5 + \(3^{x}\) = 2. ( \(4^{2} -3^{2}\) )
d) ( x + 4 \()^{2}\) - \(7^{10} : 7^{8}\) = 0
e) \(\dfrac{3}{4}x + 1 = -2\)
g) \(\dfrac{2}{3} + \dfrac{1}{3} : x = -1\)
h) \(\dfrac{x - 1}{4} = \dfrac{1}{-2}\)
k) \(2. (\dfrac{1}{2}x - \dfrac{1}{3}) + \dfrac{3}{2} = \dfrac{1}{4}\)
