Question

3 1/3 x + 16 3/4 = -13,25

Answer 1

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

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

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

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

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

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

\(\Rightarrow x=-9\)

Vậy: ...

Answer 2

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

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

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

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

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

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

Answer 3

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

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

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

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

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