✔ 最佳答案
3A+5A=6A+16

8A=6A+16

8A-6A=6A+16-6A

2A=16

2A/2=16/2

A=8

3A + 5A = 6A +16
8A=6A+16
8A-6A=16
2A=16
A=8

3A +5A =6A +16
3A+5A-6A=16
8A-6A=16
2A=16
A=8

所以A是8。

3A + 5A = 6A +16
8A=6A+16
8A-6A=6A+16-6A
2A=16
2A/2=16/2
A=8

A=8

3A+5A
=24+40
=64

6A+16
=48+16
=64

你見到依d問題個陣3A+5A其實分開睇係:(3)(A)+(5)(A)
個A係可以抽出黎:A(3+5)=8A
6A轉過去個陣正負要反轉+6A變-6A
8A-6A=16
A(8-6)=16
2A=16
依家係2乘A
個2可以轉過去,乘or除轉過去個陣會相反
A=16除2
A=8
當你見到一d加數有相同既野
eg.8B+4A
=(4x2)B+(4)A
=2(2B+A)

2010-05-19 11:55:10 補充:
=(4x2)B+(4)A
=4(2B+A)
打錯

3A + 5A = 6A +16
3A+5A-6A=16
2A=16
A=8

所以A=8.

我唔知題解有冇分...但係寫好過唔寫~
