TÌM X BIẾT

 

2/3 . X - 1/2 .X = -1/3

 

Answer 1

2/3.x-1/2.x=-1/3

(2/3-1/2).x =-1/3

1/6.x         =-1/3

x               = -1/3:1/6

x               =-2

Vậy x=-2

mọi người k cho mik hết âm nhé

Answer 2

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

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

\(\frac{1}{6}\cdot x=-\frac{1}{3}\)

\(x=-\frac{1}{3}:\frac{1}{6}\)

\(x=-2\)

Answer 3

X . ( 2/3 - 1/2 ) = -1/3

X . ( 4/6 + -3/6 ) = -1/3

X . 1/6 = -1/3

X= -1/3 : 1/6 = -1/3 .6

X= -6/3 = -2

Vậy X = -2
