10/3 y + 67/4= -1325/100

10/3y= -1325/100 - 1675/100

10/3y = -3000/100

10/3y = 30

y= 30 : 10/3

y=9

10/3y+67/4=-1325/100

10/3y=-1235/100-67/4

10/3y=-30

y=-30:10/3

y=-9

Vậyy=-9

Mik làm giống với bạn "ko quan tâm" nhưng kết quả ra -1. Mik hỏi cô rồi, đúng đó. Chúc bạn học tốt !

\(3\dfrac{1}{3}x+16\dfrac{3}{4}=-13,25\)

\(\Rightarrow\dfrac{10}{3}x+\dfrac{67}{4}=-\dfrac{53}{4}\)

\(\Rightarrow\dfrac{10}{3}x=-\dfrac{53}{4}-\dfrac{67}{4}\)

\(\Rightarrow\dfrac{10}{3}x=\dfrac{-120}{4}\)

\(\Rightarrow\dfrac{10}{3}x=-30\)

\(\Rightarrow x=-30:\dfrac{10}{3}\)

\(\Rightarrow x=-9\)

Vậy: ...

\(3\dfrac{1}{3}x+16\dfrac{3}{4}=-13,25\)

\(\Leftrightarrow\dfrac{10}{3}x+\dfrac{67}{4}=\dfrac{-53}{4}\)

\(\dfrac{10}{3}x=\dfrac{-53}{4}-\dfrac{67}{4}\)

\(\dfrac{10}{3}x=\dfrac{-120}{4}=-30\)

\(x=-30.\dfrac{3}{10}\)

\(x=\dfrac{-90}{10}=-9\)

\(\dfrac{31}{3}x+16\dfrac{3}{4}=-13,25\)

\(\dfrac{31}{3}x=\dfrac{-53}{4}-\dfrac{67}{4}\)

\(\dfrac{31}{3}x=-30\)

\(\Rightarrow x=-30:\dfrac{31}{3}\)

\(\Rightarrow x=\dfrac{-90}{31}\)

=>10/3x=3,5

=>x=21/20

4/16 và 3/4

\(1\frac{1}{3}\cdot x+16\frac{3}{4}=13,25\)

\(\frac{4}{3}\cdot x=13,25-16\frac{3}{4}\)

\(\frac{4}{3}\cdot x=-3,5\)

\(x=-3,5:\frac{4}{3}\)

\(x=-2,625\)

\(3\frac{1}{3}x+16\frac{3}{4}=-13,25\)

\(=>\frac{10}{3}x+\frac{67}{4}=\frac{-53}{4}\)

\(\frac{10}{3}x=-30\)

x = -30 : \(\frac{10}{3}\)

= > x = -9
