11a+11b
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
Gathering like terms together, this is equal to 5a + 3b + 7c.
-6(a-3b-9c)
11a+11b
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
12a + 6b + 6c = 6(2a + b + c)
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
A level 5a is higher. This is how it works: n 1c 1b 1a 2c 2b 2a 3c 3b 3a 4c 4b 4a 5c 5b 5a ect. Student from BGP. N.S.S
