Question

tìm x biết

2/3+1/6.(2,x+2)=5/6

Answer 1

=>1/6(2x+2)=5/6-2/3=1/6

=>2x+2=1

hay x=-1/2

Answer 2

2/3 + 1/6 . (2x + 2 ) = 5/6

=> 1/6 (2x + 2 ) = 5/6 - 2/3 = 1/6 

=> 2x + 2 = 1

hay x = - 1/2

Answer 3

\(2,x\) là sao :vvvv

\(\dfrac{2}{3}+\dfrac{1}{6}\cdot\left(2x+2\right)=\dfrac{5}{6}\)

\(\dfrac{1}{6}\cdot\left(2x+2\right)=\dfrac{5}{6}-\dfrac{2}{3}\)

\(\dfrac{1}{6}\cdot\left(2x+2\right)=\dfrac{5}{6}-\dfrac{4}{6}=\dfrac{1}{6}\)

\(2x+2=\dfrac{1}{6}:\dfrac{1}{6}\)

\(2x+2=1\)

\(2x=1-2\)

\(2x=-1\)

\(x=\left(-1\right):2\)

`=>x=-1/2`
