Answer 2

To solve the expressions you provided, let's work through them step by step:

2. 186 - 5b: To simplify this expression, we subtract 5b from 186. The result will depend on the value of 'b.'

If 'b' is a number, the expression cannot be further simplified without knowing the specific value of 'b.' So the result would be: 186 - 5b.

4. 19b - 5b: Here, we have 19b minus 5b. To simplify, we can combine like terms. In this case, the terms 'b' can be combined.

19b - 5b is equal to (19 - 5) * b, which simplifies to 14b.

So the simplified expression is: 14b.
