Question

Tìm x biết

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

b, 7x - 3x = 3,2

Answer 1

a) 2/3x-1/2x=15/12

=> x.(2/3-1/2)=15/12

=> x.1/6       =15/12

=> x             =15/12:1/6

=> x             =5/24

b) 7x-3x=3,2

=> x.(7-3) =3,2

=> x.4      =3,2

=> x         =3,2:4

=> x         =0,8

Answer 2

a,2/3.x - 1/2 . x = 5/12

 x . ( 2/3 - 1/2 ) = 5/12

x . 1/6 = 5/12

x = 5/12 : 1/6 

x = 15/1

Answer 3

x= 15/1

Answer 4

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

<=> \(\frac{4}{6}x-\frac{3}{6}x=\frac{5}{12}\)

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

<=>\(x=\frac{5}{2}\) nhớ k cho mik nha

câu b)

7x-3x=3,2

<=> 4x=3,2

<=>X=\(\frac{4}{5}\) đúng nhá Nguyễn Thị Hoài Thương

Answer 5

x=15/1

Answer 6

Tìm x : 3/4 : 4x - 5/12 = 1
