bn ơi đề có sai không z

0,5x - \(\dfrac{2}{3}\)x = \(\dfrac{5}{12}\)

\(\dfrac{5}{10}\)x - \(\dfrac{2}{3}\)x = \(\dfrac{5}{12}\)

(\(\dfrac{1}{2}\) - \(\dfrac{2}{3}\)) .x=\(\dfrac{5}{12}\)

(\(\dfrac{3}{6}\)

mk ấn nhầm nút, lm tiếp nha

( \(\dfrac{3}{6}\)- \(\dfrac{4}{6}\)).x=\(\dfrac{5}{12}\)

\(\dfrac{-1}{6}\).x=\(\dfrac{5}{12}\)

x =\(\dfrac{5}{12}\): \(\dfrac{-1}{6}\)

x = \(\dfrac{5}{12}\). \(\dfrac{6}{-1}\)

x = \(\dfrac{30}{-12}\)

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

=>(0.5-2/3)x=5/12

=>-1/6x=5/12

=>x=5/12:-1/6

=>=-5/2

vậy x=-5/2

tui biết nè

0.5x-2/3x=5/12

=>x(0.5-2/3)=5/12

=>x*(-1/6)=5/12

=>X=(5/12)/(-1/6)

=>x=-5/2

\(0,5x-\frac{2}{3}x=\frac{5}{12}\)

\(x\left(0.5-\frac{2}{3}\right)=\frac{5}{12}\)

\(x.\left(-\frac{1}{16}\right)=\frac{5}{12}\)

\(x=\frac{5}{12}:-\frac{1}{16}=-2.5\Leftrightarrow-\frac{5}{2}\)

\(0,5x-\frac{2}{3}x=\frac{5}{12}\)

\(\frac{1}{2}x-\frac{2}{3}x=\frac{5}{12}\)

\(\left(\frac{1}{2}-\frac{2}{3}\right)x=\frac{5}{12}\)

\(-\frac{1}{6}x=\frac{5}{12}\)

\(\Rightarrow x=\frac{5}{12}\div\left(-\frac{1}{6}\right)\)

\(x=-\frac{5}{2}\)

0,5x - 2/3x = 5/12

1/2x - 2/3x =5/12

[1/2 - 2/3]x  = 5/12

-1/6x            = 5/12

x                  = 5/12 : [-1/6 ]

x           =          5/2

1/2x=5/12+2/3

1/2x=13/12

x=13/12:1/2

x=6/13

Vậy x  = 6/13

\(0,5-\frac{2}{3}x=\frac{5}{12}\)

\(=\frac{1}{2}x=\frac{5}{12}+\frac{2}{3}\)

\(=\frac{1}{2}x=\frac{13}{12}\)

\(\Rightarrow x=\frac{13}{12}:\frac{1}{2}\)

\(\Rightarrow x=\frac{6}{13}\)

Vậy x = \(\frac{6}{13}\)

(#)

:3

x. (0,5-2/3)= 5/12

x. -1/6= 5/12

x= 5/12 : -1/6

x= -5/2

=> (1 / 2 - 2 / 3 ) x =5 / 12

=> - 1 / 6 x = 5 / 12

=> x = 5 / 12 : -1 / 6

=> x = -5 / 2

NHO K CHO MIH DO NHA

x(0.5-2/3)=5/12

x(1/2-2/3)=5/12

x*1/12=5/12

       x =5/12:1/12

       x=5

Vậy x=5

\(0,5x-\frac{2}{3}x=\frac{5}{12}\)

\(\frac{1}{2}x-\frac{2}{3}x=\frac{5}{12}\)

\(x.\left(\frac{1}{2}-\frac{2}{3}\right)=\frac{5}{12}\)

\(\Rightarrow x=-\frac{5}{2}\)

đúng chứ bn 

\(0,5x-\frac{2}{3}x=\frac{7}{12}\)

\(\Rightarrow x\left(0,5-\frac{2}{3}\right)=\frac{7}{12}\)

\(\Rightarrow-\frac{1}{6}x=\frac{7}{12}\)

\(\Rightarrow x=-\frac{7}{2}=-3,5\)

\(\frac{1}{2}x-\frac{2}{3}x=\frac{7}{12}\)

\(\Leftrightarrow-\frac{1}{6}x=\frac{7}{12}\)

\(\Leftrightarrow x=\frac{7}{12}:-\frac{1}{6}\)

\(\Leftrightarrow x=-\frac{7}{2}\)
