Question

5+x/12=2/3 cả cách làm 

Answer 1

=>x+5=8

hay x=3

Answer 2

52/12

Answer 3

\(\dfrac{x}{12}=\dfrac{2}{3}-5\)

\(\dfrac{x}{12}=\dfrac{-13}{3}\)

\(x=\dfrac{-13}{3}\times12\)

\(x=-52\)

Answer 4

\(5+\dfrac{x}{12}=\dfrac{2}{3}\)

        \(\dfrac{x}{12}=\dfrac{2}{3}-5\)

         \(\dfrac{x}{12}=-\dfrac{13}{3}=-\dfrac{52}{12}\)

Answer 5

x/12=2/3-5

x/12=-13/3

x/12=-13/3 x 4

x/12= -52/12

x=-52

Answer 6

\(5+\dfrac{x}{12}=\dfrac{2}{3}\)

\(\Rightarrow\dfrac{x}{12}=\dfrac{2}{3}-5\)

\(\Rightarrow\dfrac{x}{12}=-\dfrac{13}{3}\)

\(\Rightarrow x=-13\) x \(12:3=-52\)
