Đáp án:

Giải thích các bước giải:

$a,-\dfrac{13}{24}+x=\dfrac{9}{20}$

$⇔x=\dfrac{9}{20}+\dfrac{13}{24}$

$⇔x=\dfrac{119}{20}$

$b,x+\dfrac{13}{15}=-\dfrac{2}{5}$

$⇔x=-\dfrac{2}{5}-\dfrac{13}{15}$

$⇔x=-\dfrac{19}{15}$

$c,\dfrac{29}{30}-x=\dfrac{43}{60}$

$⇔x=\dfrac{29}{30}-\dfrac{43}{60}$

$⇔x=\dfrac{1}{4}$

$d,x-\dfrac{30}{75}=\dfrac{16}{20}$

$⇔x=\dfrac{4}{5}+\dfrac{2}{5}$

$⇔x=\dfrac{6}{5}$

$d,\dfrac{1}{9}-\dfrac{x}{6}=-\dfrac{13}{18}$

$⇔\dfrac{x}{6}=\dfrac{1}{9}+\dfrac{13}{18}$

$⇔\dfrac{x}{6}=\dfrac{5}{6}$

$⇔x=5$
