✔ 最佳答案
( A + B ) - C = 2600而家 A = 5000, 即係C - B = 5000 - 2600 = 2400
所以B 比C 少$2400.

５０００＋ｂ－ｃ＝２６００
ｂ－ｃ＝２６００－５０００
ｂ－ｃ＝－２４００
ｂ＝－２４００＋ｃ
ｓｏ
５０００＋（－２４００）＋ｃ－ｃ＝２６００
２６００＝２６００

設A,B,C 的儲蓄分別為$a,$b,$c
a+b=c+2600
已知 a=5000
5000+b=c+2600
c=b+2400
所以, B 比 C 少 $2400
a+b=c+2600
已知 a=5000
5000+b=c+2600
c=b+2400
所以, B 比 C 少 $2400

A + B = C + 2600 (Ａ同Ｂ既儲蓄比Ｃ多元$2600)
5000 + B = C + 2600 ( 如果A有$5000 )
C - B = 5000 - 2600 ( B比C少 )
C - B = 2400
I hope I didn't misunderstand ur question...
