Tìm x

\(\frac{-5}{6}x-1\frac{13}{19}:3\frac{7}{19}-\left(-0,12\right)\)\(=\left(\frac{-1}{2}\right)^2\)

Answer 1

[Khánh Ngọc]

\(-\frac{5}{6}x-1\frac{13}{19}:3\frac{7}{19}-\left(-0,12\right)=\left(-\frac{1}{2}\right)^2\)

\(\Rightarrow-\frac{5}{6}x-\frac{32}{19}:\frac{64}{19}+0,12=\frac{1}{4}\)

\(\Rightarrow-\frac{5}{6}x-\frac{1}{2}=\frac{1}{4}-0,12=\frac{13}{100}\)

\(\Rightarrow-\frac{5}{6}x=\frac{63}{100}\)

\(\Rightarrow x=-\frac{189}{250}\)

Answer 2

[ミ★luffy☆mũ☆rơm★彡]

-5/6x-32/19:64/19+3/25=1/4

-5/6x-32/19×19/64+3/25=1/4

-5/6x-1/2+3/25=1/4

-5/6x-31/50=1/4

-5/6x=1/4+31/50

-5/6x=87/100

x=87/100:-5/6

x=87/100×-6/5

x=-261/250

vậy x=-261/250
