Tìm x

3/2 - ( x - 2 1/3) = |-3/4 - 1 1/8|

Nguyễn Thanh Hằng · Accepted Answer

$\dfrac{3}{2}-\left(x-2\dfrac{1}{3}\right)=\left|\dfrac{-3}{4}-1\dfrac{1}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-2\dfrac{1}{3}\right)=\left|\dfrac{-3}{4}-\dfrac{9}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-\dfrac{7}{3}\right)=\left|\dfrac{-15}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-\dfrac{7}{3}\right)=\dfrac{15}{8}$

$\Leftrightarrow x-\dfrac{7}{3}=\dfrac{3}{2}-\dfrac{15}{8}$

$\Leftrightarrow x-\dfrac{7}{3}=\dfrac{-3}{8}$

$\Leftrightarrow x=\dfrac{-3}{8}+\dfrac{7}{3}=\dfrac{47}{24}$

Vậy ...Câu trả lời: $\dfrac{3}{2}-\left(x-2\dfrac{1}{3}\right)=\left|\dfrac{-3}{4}-1\dfrac{1}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-2\dfrac{1}{3}\right)=\left|\dfrac{-3}{4}-\dfrac{9}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-\dfrac{7}{3}\right)=\left|\dfrac{-15}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-\dfrac{7}{3}\right)=\dfrac{15}{8}$

$\Leftrightarrow x-\dfrac{7}{3}=\dfrac{3}{2}-\dfrac{15}{8}$

$\Leftrightarrow x-\dfrac{7}{3}=\dfrac{-3}{8}$

$\Leftrightarrow x=\dfrac{-3}{8}+\dfrac{7}{3}=\dfrac{47}{24}$

Vậy ...

$\dfrac{3}{2}-\left(x-2\dfrac{1}{3}\right)=\left|\dfrac{-3}{4}-1\dfrac{1}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-\dfrac{7}{3}\right)=\left|\dfrac{-15}{8}\right|$

$\Leftrightarrow\dfrac{3}{2}-\left(x-\dfrac{7}{3}\right)=\dfrac{15}{8}$

$\Leftrightarrow x-\dfrac{7}{3}=\dfrac{-3}{8}$

$\Leftrightarrow x=\dfrac{-3}{8}+\dfrac{7}{3}$

$\Rightarrow x=\dfrac{47}{24}$

Vậy $x=\dfrac{47}{24}$
