18-(x:2+2) = 12
18 - x/2 - 2= 12
18 - 2 -x/2 = 12
16 - x/2 = 12
x/2 = 4
x = 8
18-(x : 2 + 2)=12
=>x : 2 + 2 =6
=>x : 2 = 4
=> x = 8
18-(x:2+2)=12
x:2+2=18-12
x:2=6-2
x:2=4
x=4x2
x=8
Vậy x=8
Tham khảo nhé~
18-(x:2+2)=12
=>x:2+2=18-12
x:2+2=6
x:2=6-2
x:2=4
x=4 x 2
x=8
18 - ( x : 2 + 2 ) = 12
x : 2 + 2 = 18 - 12
x : 2 + 2 = 6
x : 2 = 4
x = 2
18 - ( x : 2 + 2 ) = 12
x : 2 + 2 = 18 - 12
x : 2 + 2 = 6
x : 2 = 6 - 2
x : 2 = 4
x = 4 x 2
x = 8
18 - ( x : 2 + 2 ) = 12
x : 2 + 2 = 18 - 12
x : 2 + 2 = 6
x : 2 = 6 - 2
x : 2 = 4
x = 4 * 2
x = 8
18 - ( x : 2 + 2 ) = 12
x : 2 + 2 = 18 - 12
x : 2 + 2 = 6
x : 2 = 6 - 2
x : 2 = 4
x = 4 x 2 = 8
4 ai k mình thì mình sẽ kb
18 -(x : 2 + 2 ) =12
x : 2 +2 = 18 - 16
x : 2 + 2 = 6
x :2 = 6 - 2
x : 2 = 4
x = 4 x 2
x = 8
vậy x = 8
18 - ( x : 2 + 2 ) = 12
x : 2 + 2 = 18 - 12
x : 2 + 2 = 6
x : 2 = 6 - 2
x : 2 =4
x = 4 : 2
x = 2
Vậy x= 2
18 - ( x : 2 + 2 ) = 12
x : 2 + 2 = 18 - 12
x : 2 + 2 = 6
x : 2 = 4
x = 2
