Answer 2

To solve the given expression, let's break it down step by step:

4b - 2: This expression represents "4 times b minus 2."

5b: This expression represents "5 times b."

20 - 1: This expression represents "20 minus 1."

1 + 5b: This expression represents "1 plus 5 times b."

5b: This expression represents "5 times b."

Now let's substitute the values of b into the expressions:

For example, if b = 3:

4b - 2 = 4(3) - 2 = 12 - 2 = 10

5b = 5(3) = 15

20 - 1 = 19

1 + 5b = 1 + 5(3) = 1 + 15 = 16

5b = 5(3) = 15

So, the final expression becomes:

10 15 19 16 15
