Not particularly, but yes sometimes.
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
Given the equation ( (3a - 4) + (3b - 4) + (3c - 4) = 2016 ), we can simplify it to ( 3a + 3b + 3c - 12 = 2016 ), leading to ( 3a + 3b + 3c = 2028 ). Dividing by 3 gives ( a + b + c = 676 ). Now, to find ( (4a - 3) + (4b - 3) + (4c - 3) ), we can express it as ( 4(a + b + c) - 9 = 4(676) - 9 = 2704 - 9 = 2695 ). Thus, the sum is 2695.
It is an expression of two terms as: 4a+12
-4a = 48 a = -12
The answer is 4a + 12
5ab-2ab+4a-b+5b = 3ab+4a+4b

It depends on the exact form. If it is 4a + 12/(a + 3) then a cannot be -3 However, (4a + 12)/(a + 3) simplifies to 4. So there is no variable to worry about!
The question contains neither an expression nor an equation (or inequality). There can, therefore be no sensible answer.
8a+4a=144 12a=144 12a/12=144/12 A=144
