7/4 - y x 5/6 = 1/2 + 1/3
7/4 - y x 5/6 = 5/6
y x 5/6 = 7/4 - 5/6
y x 5/6 = 11/12
y = 11/12 : 5/6
y = 11/12 x 6/5
y = 11/10
Vậy y = 11/10
2/3 + 12/7 : x = 7/5
12/7 : x = 7/5 - 2/3
12/7 : x = 11/15
x = 12/7 : 11/15
x = 12/7 x 15/11
x = 180/77
Vậy x = 180/77

=> (x+6) x 27 = 24 x27
(x+6) x 27 =648
x+6 =648 : 27
x+6= 24
x=24 - 6
x= 18
Vậy x = 18

=2/3 x 9/7 x 4/15 +5/7
= 6/7 x 4/15 + 5/7
= (6/7+5/7) x 4/15
= 11/7 x 4/15
=44/105
