23 - 27 - 16 -(-19)
23 + (-27) + 16 +32

Answer 1

The expression 23 - 27 - 16 + 32 is not equivalent to the original expression.

Step-by-step explanation:

To determine which of the given expressions is not equivalent to 23 + (-27) - 16 - (-23), we need to simplify each expression and compare the result to the original expression.

Let's start by simplifying the original expression:

1. 23 + (-27) = -4
2. -4 - 16 = -20
3. -20 - (-23) = 3

Now, let's simplify each of the given expressions:

1. 23 + (-27) + (-16) + (-32) = -52
2. 23 - 27 - 16 + 32 = 12
3. 23 - 27 - 16 - (-19) = 29
4. 23 + (-27) + 16 + 32 = 44

Comparing the simplified expressions to the original expression, we can see that 23 - 27 - 16 + 32 is not equivalent to the original expression.
