Tính giá trị của biểu thức:

\(A=\dfrac{-3}{7}.\dfrac{5}{9}+\dfrac{4}{9}.\dfrac{-3}{7}+\left(-2022\right)^0\)

\(B=0,75-\left(2\dfrac{1}{3}+0,75\right)+3^2.\left(-\dfrac{1}{9}\right)\)

\(C=2\dfrac{6}{7}.\left[\left(\dfrac{-7}{5}-\dfrac{3}{2}:\dfrac{-5}{-4}\right)+\left(\dfrac{3}{2}\right)^2\right]\)

\(D=\dfrac{2}{7}+\dfrac{5}{7}.\left(\dfrac{3}{5}-0,25\right).\left(-2\right)^2+35\%\)

\(E=1\dfrac{13}{15}.0,75-\left(\dfrac{11}{20}+25\%\right):1\dfrac{2}{5}\)

\(F=\dfrac{\dfrac{5}{3}-\dfrac{5}{7}+\dfrac{5}{9}}{\dfrac{10}{3}-\dfrac{10}{7}+\dfrac{10}{9}}\)

Tìm x:

a) (2x - 3)(6 - 2x) = 0

b) \(5\dfrac{4}{7}:x=13\) 

c) 2x - \(\dfrac{3}{7}\) = \(6\dfrac{2}{7}\)

d) \(\dfrac{x}{5}\) + \(\dfrac{1}{2}\) = \(\dfrac{6}{10}\)

e) \(\dfrac{x+3}{15}=\dfrac{1}{3}\)

f) \(\dfrac{x-12}{4}=\dfrac{1}{2}\)

g) \(2\dfrac{1}{4}\).\(\left(x-7\dfrac{1}{3}\right)=1,5\)

h) \(\left(4,5-2x\right).1\dfrac{4}{7}=\dfrac{11}{14}\)

i) \(\dfrac{2}{3}\left(x-25\%\right)=\dfrac{1}{6}\)

k) \(\dfrac{3}{2}x-1\dfrac{1}{2}=x-\dfrac{3}{4}\)
