６ａ－（５ａ－４ｂ）＋（３ａ－２ｂ）－ｂ
=6a-1(5a-4b)+1(3a-2b)-b
=6a-5a+4a+3a-2b-b
=a+4a+3a-3b
8a-3b
=6a-1(5a-4b)+1(3a-2b)-b
=6a-5a+4a+3a-2b-b
=a+4a+3a-3b
8a-3b

６ａ－（５ａ－４ｂ）＋（３ａ－２ｂ）－ｂ
＝６ａ－５ａ＋４ｂ＋３ａ－２ｂ－ｂ
＝１ａ＋４ｂ＋３ａ－２ｂ－ｂ
＝１ａ＋３ａ＋４ｂ－２ｂ－ｂ
＝４ａ＋（４ｂ－２ｂ－ｂ）
＝４ａ＋１ｂ
＝６ａ－５ａ＋４ｂ＋３ａ－２ｂ－ｂ
＝１ａ＋４ｂ＋３ａ－２ｂ－ｂ
＝１ａ＋３ａ＋４ｂ－２ｂ－ｂ
＝４ａ＋（４ｂ－２ｂ－ｂ）
＝４ａ＋１ｂ

6 a - ( 5 a- 4 b ) + ( 3 a - 2 b ) - b
= 6 a - f + f - b
= 5 b + f - b
= 6a - b
= 5f [ 95 ]
= 6 a - f + f - b
= 5 b + f - b
= 6a - b
= 5f [ 95 ]
