Answer 2

Let's solve the given equation step by step:

(16 + b) + 4

First, we perform the addition inside the parentheses: 16 + b = b + 16. Substituting this back into the equation:

(b + 16) + 4

Next, we perform the addition inside the parentheses: b + 16 + 4 = b + 20. Therefore, the simplified expression is:

b + 20

Now let's consider the second part of the equation:

(16 + 4) + b

Performing the addition inside the parentheses: 16 + 4 = 20. Substituting this back into the equation:

20 + b

Therefore, the simplified expression is:

b + 20

In both cases, we end up with the same expression: b + 20. So, (16 + b) + 4 is equal to (16 + 4) + b, and both expressions simplify to b + 20.

Answer 3

Let's solve the given equation step by step:

(16 + b) + 4 = (16 + 4) + b

First, let's simplify the expressions within the parentheses:

16 + b + 4 = 20 + b

Now, we have:

20 + b = 20 + b

The equation simplifies to 20 + b on both sides. Since the left side is equal to the right side, the equation is an identity. This means that for any value of b, the equation will hold true.
