a) 2/3 . x – 1/2 . x = 5/12 (2/3 – 1/2) . x = 5/12. 1/6 . x = 5/12 x = 5/12 : 1/6 x = 5/12 . 6/1 x = 5/2 Bình luận
a, 2/3.x – 1/2.x = 5/12
(2/3 – 1/2).x = 5/12
1/6.x = 5/12
x = 5/12 : 1/6
x = 5/2
a) 2/3 . x – 1/2 . x = 5/12
(2/3 – 1/2) . x = 5/12.
1/6 . x = 5/12
x = 5/12 : 1/6
x = 5/12 . 6/1
x = 5/2
