( 17 - x ) - 12 = 6
17 - x = 6 + 12
17 - x = 20
x = 20 - 17
x = 3
VERY GOOD!!!
ta có: (17 - x ) - 12 = 6
\(\Rightarrow\)17 - x = 6 + 12 = 18
\(\Rightarrow\)x = 17 - 18 = -1
Vậy : x = -1
( 17 - x ) - 12 = 6
=>17 - x = 6 + 12
=> 17 - x = 18
=> x = 17 - 18
=> x = - 1
Vậy : x = - 1
(17-x)-12=6
17-x=12+6
17-x=18
x=17-18
x=-1
\(\left(17-x\right)-12=6\)
\(\Rightarrow5-x=6\)
\(\Rightarrow x=5-6=-1\)
Trịnh Thị Thanh Hiền ơi 12 + 6 = 18 nhé
18 not 20 oke :)))
ban bangtansonyondan lam dung roi nhung ban chua day du nen mk se k cho nguoi khac nha
( 17 - x) - 12 = 6
17-x = 6+12
17-x =18
x =17-18
x =-1
vậy x =-1 nhé
( 17 - x ) - 12 = 6
( 17 - x ) = 6 + 12
17 - x = 18
x = 17 - 18
x = (-1)
Vậy x = ...
