c)$ (7x-23 )+ 47= -11^{}$
(7x-23 ) = -11 - 47
(7x-23 ) = -58
7x = -58 + 23
7x = -35
x = -35 : 7
$ x = -5^{}$
Vậy x = -5
d) $32 - (5x - 18) = 95^{}$
(5x - 18) = 32 - 95
(5x - 18) = - 63
5x = -63 +18
5x = -45
x = -45 : 5
$x = -9^{}$
Vậy x = -9
e) $11 - ( 20 + 12 = x - (25 - 9)^{}$
11 - 32 = x - (25- 9)
- 21 = x - 16
=> x -16 = -21
x = -21 + 16
$ x = -5^{}$
Vậy x = -5
