✔ 最佳答案
k/6-1=2(我唔知你個-1係放係邊,如果放係出面就咁計)k/6-1+1=2+1
k/6 x 6=3 x 6
k=18
如果放係入面就
k-1/6=2
k-1/6 x 6=2x6
k-1=12
k=13
5+c/3=4(5+唔同c一齊就咁計)
5+c/3-5=4-5
c/3 x 3 = -1x3
c=-3
同c一齊就咁計
(5+c)/3=4
(5+c)/3 x 3=4x3
5+c=12
5+c-5=12-5
c=7
9d/2-8=1
9d/2-8+8=1+8
9d/2 x 2=9x2
9d=18
d=2

k/6-1 =2
=> k-6=12
=> k=18
5+C/3 =4
=> 15+C =12
=> C= -3
9D/2 -8 =1
=> 9D -16 =2
=> 9D = 18
=> D=2
=> k-6=12
=> k=18
5+C/3 =4
=> 15+C =12
=> C= -3
9D/2 -8 =1
=> 9D -16 =2
=> 9D = 18
=> D=2

1:
K/6-1=2
K/6=3
6X3=18
so,K=18
3:
9D/2-8=1
9D/2=9
9D=18
D=2
2007-10-08 18:03:09 補充：
C/(5 3)=4C/8=42/8=CC=4
K/6-1=2
K/6=3
6X3=18
so,K=18
3:
9D/2-8=1
9D/2=9
9D=18
D=2

我唸係
a) k/6 -1 = 2
b) c/(5+3) = 4
c) 9d/2 -8 =1
p.s. -1 同 -8吾係個分母。

1) k/6 - 1 = 2
k/6 = 2 + 1
k = 3 x 6
k = 18
2) 5 + c/3 = 4
c/3 = 4 - 5
c = - 1 x 3
c = - 3
3) 9D/2 - 8 = 1
9D/2 = 1 + 8
9D = 9 x 2
D = 18除9
D = 2
k/6 = 2 + 1
k = 3 x 6
k = 18
2) 5 + c/3 = 4
c/3 = 4 - 5
c = - 1 x 3
c = - 3
3) 9D/2 - 8 = 1
9D/2 = 1 + 8
9D = 9 x 2
D = 18除9
D = 2
