Answer 2

It seems like you have provided several algebraic expressions, and it's unclear if you want to simplify them or perform some specific operation. I'll go through each expression step by step:

1. X + 3x + 4x - 5x + 7x: Combine like terms (terms with the same variable, in this case, "x"): X + 3x + 4x - 5x + 7x = (1 + 3 + 4 - 5 + 7)x = 10x

So, the simplified expression is 10x.

2. 14a - 12b - a - b: Combine like terms (terms with the same variable): 14a - a - 12b - b = (14 - 1)a + (-12 - 1)b = 13a - 13b

So, the simplified expression is 13a - 13b.

If you have any specific operations or questions related to these expressions, please provide more details, and I'll be happy to assist you further.
