Question

Which equation is true? A. 7 - 3 = 3 - 7 B. 7 - 3 = -7 + 3 C. 7 - 3 = 7 + (-3) D. 7 - 3 = -7 - 3

Answer 1

In the provided options, the correct equation is 7 - 3 = 7 + (-3). This equation is true because both sides simplify to 4.

Step-by-step explanation:

The question asks us to determine which equation is true. Let's evaluate each option:

1. 7 - 3 = 3 - 7. This simplifies to 4 ≠ -4, so it's not true.
2. 7 - 3 = -7 + 3. This simplifies to 4 ≠ -4, so it's also not true.
3. 7 - 3 = 7 + (-3). In this case, both sides simplify to 4. Therefore, this equation is true.
4. 7 - 3 = -7 - 3. This simplifies to 4 ≠ -10, so it's not true.

So the correct answer is C. 7 - 3 = 7 + (-3). Also, it's important to remember that in an equation, both sides need to have the same value for it to be true.
