Tìm $x :$
$a) x - \dfrac{1}{2}$ = $\dfrac{1}{3} - \dfrac{5}{6}$
$x - \dfrac{1}{2}$ = $\dfrac{-1}{2}$
$x = \dfrac{-1}{2}$ + $\dfrac{1}{2}$
$x = 0$
$b) \dfrac{5}{3} - x =$ $\dfrac{1}{4} - \dfrac{4}{3}$
$ \dfrac{5}{3} - x =$ $\dfrac{-13}{12}$
$x = \dfrac{5}{3} - \dfrac{-13}{12}$
$x = \dfrac{11}{4}$
$c) \dfrac{4 - 1}{2} . x =$ $\dfrac{1}{5} : \dfrac{1}{10}$
$ \dfrac{4 - 1}{2} . x = 2$
$ \dfrac{1}{2} . x = 4 - 2$
$x = 2 : $ $\dfrac{1}{2}$
$x = 4$
$d) x - \dfrac{3}{2}$ = $\dfrac{5}{7} : \dfrac{-5}{14}$
$x - \dfrac{3}{2}$ = $-2$
$x =$ $-2$ + $\dfrac{3}{2}$
$x = \dfrac{-1}{2}$

A. X-1/2=1/3-5/6 B. 5/3 - X = 1/4 - 4/3 C. 4-1/2 . X = 1/5 : 1/10
X-1/2=-1/2 5/3-X=-13/12 4-1/2.X = 2
X=-1/2+1/2 X=5/3-13/12 1/2.X=4-2
X=0 X=11/4 X=2:1/2
X=4
D. x - 3/2 = 5/7 : - 5/14
X-3/2=-2
X=-2+3/2
X=-1/2
