Lời giải:
$-34+(5-1\frac{2}{3}x):\frac{1}{2}=14$
$-34+(5-\frac{5}{3}x):\frac{1}{2}=14$
$(5-\frac{5}{3}x):\frac{1}{2}=14+34=48$
$5-\frac{5}{3}x=48.\frac{1}{2}=24$
$\frac{5}{3}x=5-24=-19$
$x=-19:\frac{5}{3}=\frac{-57}{5}$
\(-34+\left(5-1\dfrac{2}{3}x\right):\dfrac{1}{2}=14\)
=>\(-34+\left(5-\dfrac{5}{3}x\right):\dfrac{1}{2}=14\)
=>\(-34+\left(\dfrac{10}{3}x\right)=14.\dfrac{1}{2}\)
=>\(-34+\dfrac{10}{3}x=7\)
=>x=123/10=12,3
