Understanding the Concept of Checking Equations

When it comes to solving equations, it's essential to verify the answer to ensure accuracy. One way to do this is by using the concept of inverse operations. Inverse operations are pairs of mathematical operations that undo each other. For example, addition and subtraction are inverse operations, as are multiplication and division.

The Given Equation: 205 - 110 = 95

The equation provided is a simple subtraction problem. To check the answer, we need to find an equivalent equation that uses the same numbers but with a different operation. Let's examine the given choices and determine which one can be used to check the answer.

Choice A: 110 + 95 = 205

This choice involves adding 95 and 110, which is the inverse operation of the original subtraction problem. By adding 95 and 110, we should get the original number, 205. This choice can be used to check the answer because it uses the inverse operation of subtraction, which is addition.

Choice B: 205 + 110 = 315

This choice involves adding 205 and 110, which is not the inverse operation of the original subtraction problem. Instead, it's a simple addition problem that doesn't relate to the original equation. This choice cannot be used to check the answer.

Choice C: 205 + 110 + 95 = 410

This choice involves adding 205, 110, and 95, which is not the inverse operation of the original subtraction problem. Instead, it's a simple addition problem that doesn't relate to the original equation. This choice cannot be used to check the answer.

Choice D: 205 + 95 = 300

This choice involves adding 205 and 95, which is not the inverse operation of the original subtraction problem. Instead, it's a simple addition problem that doesn't relate to the original equation. This choice cannot be used to check the answer.

Conclusion

Based on the analysis, only Choice A can be used to check the answer in the equation 205 - 110 = 95. This is because it uses the inverse operation of subtraction, which is addition. By adding 95 and 110, we can verify that the answer is indeed 205.
