✔ 最佳答案
12p=36
p=36/12
p=3


h-15=14
h=14+15
h=29

w+7=20
w=20-7
w=13

3=a/9Z這是分數?????
係3=a/9???定係3=a/(9z)????定係3=(a/9)z???????

第一題,p=3
第二題,h=29
第三題,w=13
第四題,a=27
仲有,其實方程唔難,多practise就得了。

1)12p=36

1)12p除(即分線)12=36除12
2)約簡
3)p=3
4)得出答案

2)h-15=14

1)h-15+15=14+15
2)約簡
3)h=29
4)得出答案是29

3)w+7=20

1)w+7-7=20-7
2)約簡
3)w=13
4)得出答案是13

4)3=a/9

1)3乘9=a/9乘9
2)約簡
3)27=a
4)a=27(記緊要倒轉)
5)得出答案是27

p=3

h-15=14
h-15+15=14+15
h=29

w+7=20
w+7-7=20-7
w=13

3=a/9
a/9=3
a/9X9=3X9

1)12p=36 12*3=36 p=3 2)h-15=14 h=14+15 h=29 3)w+7=20 w=20-7 w=13 4)3=a/9z a=9z*3 a=27z this is the answers .if u do not know ,u can ask me and i will teach u again!haha

sorry if u say question 4 ia 3=a/9 then,3*9=a a=27
2007-08-26 12:45 am
12p=36 : p=36÷12.............p=3

h-15=14 : h=14+15.............h=29

w+7=20 : w=20-7................w=13

3=a/9 : a=3x9.................a=27
2007-08-26 12:43 am
12p = 36
p = 36/12
p = 3

h - 15 = 14
h = 14 + 15
h = 29

w + 7 = 20
w = 20 - 7
w = 14

3 = a/9
a = 3*9
a= 27
2007-08-26 12:41 am
12p=36 -> p = 3
h-15=14 -> h = 29
w+7=20 -> w = 13
3=a/9 -> a = 27
3=a/9Z -> a = 27z (個z 打錯左吧 - -)
2007-08-26 12:40 am
p=3

h=29

w=14

呢條有2個unknown做唔到-3-

最尾果條你既意恩係咪3=a/9??如果係咁,,a=27
