(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
2a + 4b
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)

(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
2a + 4b
6a+7b
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
6+7a+6b
-2a plus 3b

12a + 6b + 6c = 6(2a + b + c)
6a+7b. This cannot be simplified anymore unless you know a or b.
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
