Question

Which is correct?2 + 7 = 5 + 34 + 2 = 9 - 31 + 2 = 6 - 44 + 4 = 9 - 2

Answer 1

Let's break down the equation step by step to see if everything calculates correctly.

1. \( 2 + 7 = 9 \)

2. \( 5 + 34 + 2 = 41 \)

3. \( 9 - 31 + 2 = -20 \)

4. \( 6 - 44 + 4 = -34 \)

5. \( 9 - 2 = 7 \)

So, the equations as you presented them do not hold true. Here are the simplified computations:

- The first statement \( 2 + 7 = 9 \) is correct.
- The second statement \( 5 + 34 + 2 = 41 \) is not equal to \( 9 \).
- The third statement \( 9 - 31 + 2 = -20 \) is not equal to \( 6 \).
- The fourth statement \( 6 - 44 + 4 = -34 \) is not equal to \( 9 \).
- The last statement \( 9 - 2 = 7 \) is also correct.

Overall, the provided expressions do not maintain equality as a whole.
