Question

 cau hoi la : -2/3 . x + -3/7 + 1/2 . x = -5/6

 

Answer 1

-2/3 . x + -3/7 + 1/2 . x = -5/6

-2/3x + 1/2x - 3/7 = -5/6

(-2/3 + 1/2)x = -5/6 +3/7

-1/6x = -17/42

x= -17/42 : (-1/6)

x= 17/7

Answer 2

x.(-2/3 + 1/2) - 3/7 = -5/6

-1/6.x - 3/7 = -5/6

-1/6.x = -5/6 + 3/7

-1/6.x = -17/42

x = -17/42 : -1/6

x = 17/7

Answer 3

= x( -2/3 + -3/4+ 1/2 ) = -5/6

  x ( -11/12)= -5/6

x= 10/11

Answer 4

\(\Rightarrow x.\left(\frac{1}{2}+\frac{-2}{3}\right)+\frac{-3}{7}=\frac{-5}{6}\)

\(\Rightarrow x.\frac{-1}{6}=\frac{-5}{6}-\frac{-3}{7}\)

\(\Rightarrow x=\frac{-17}{42}:\frac{-1}{6}\)

\(\Rightarrow x=\frac{-102}{-42}\)

Answer 5

\(\frac{-2}{3}.x+\frac{1}{2}.x+\frac{-3}{7}=\frac{-5}{6}\)

\(\Rightarrow x.\left(\frac{-2}{3}+\frac{1}{3}\right)+\frac{-3}{7}=-\frac{5}{6}\)

\(\Rightarrow x.\frac{-1}{3}+\frac{-3}{7}=\frac{-5}{6}\)

\(\Rightarrow x.\frac{-1}{3}=\frac{17}{7}\)
