x = 11 + 2
11 + 2 = x
x = 13.
Vậy x = 13.
11 + x = 13
x = 13 - 11
x = 2.
Vậy x = 2.
x + 8000 = 9191
x = 9191 - 8000
x = 1191.
Vậy x = 1191.

b) ( 5/7 - 7/5 ) - [ - 1/2 - ( -2/7 - 1/10 ]
= -24/35 + 1/2 + 2/7 + 1/10
= -83/70 + 27/70
= -28/25

a) -1/24 - [ 1/4 - ( 1/2 - 7/8 )]
= -1/24 - [ 1/4 +3/8 ]
= -1/24 - 5/8
= -2/3.
