Question

[Hoàng Thúy An]

a\(\dfrac{5}{6}x-\dfrac{2}{3}=3\dfrac{1}{2}\)

b\(\dfrac{4}{5}-\dfrac{3}{4}\div x=0,3\)

c\(\dfrac{-3}{2}-\dfrac{1}{4}x=1\dfrac{1}{3}-0,2x\)

d\(\left|\dfrac{3}{5}x+\dfrac{4}{3}\right|:\dfrac{2}{3}-0,5=1\dfrac{1}{2}\)

e\(\dfrac{4x-5}{2-3x}=\dfrac{3}{4}\)

giúp mình nhé

Answer 1

[Đời về cơ bản là buồn... cười!!!]

b) \(\dfrac{4}{5}-\dfrac{3}{4}:x=0,3\)

\(\Rightarrow0,8-0,75:x=0,3\)

\(\Rightarrow0,75:x=0,5\)

\(\Rightarrow x=1,5\)

Answer 2

[Đời về cơ bản là buồn... cười!!!]

c) \(\dfrac{-3}{2}-\dfrac{1}{4}x=1\dfrac{1}{3}-0,2x\)

\(\Rightarrow\dfrac{-3}{2}-\dfrac{4}{3}=\dfrac{1}{4}x-\dfrac{1}{5}x\)

\(\Rightarrow x=\dfrac{-17}{6}\cdot20\)

\(\Rightarrow x=\dfrac{-170}{3}\)
