Good evening. I do have a math question that I really need some help on please.
(Yes or No) addition or subtraction can be used when the (coefficients or negative value) of the x-terms or the y-terms are (the same or opposites or /fractions)
My answer is:
No addition or subtraction can be used when the negative value of the x-terms and y-terms are the same or opposities. -Is this correct? I am a bit confused on what the proper answer would be.

Good evening! I'd be happy to help you with your math question.
To determine whether addition or subtraction can be used when the coefficients or negative values of the x-terms or y-terms are the same or opposites, let's break it down.
First, let's understand what coefficients and negative values are in an equation.
- Coefficients represent the numbers multiplied by the variables in an equation. For example, in the equation 5x + 3y = 10, the coefficients are 5 and 3.
- Negative values indicate that the term is subtracted rather than added. For example, in the equation 2x - 4y = 8, the negative value is -4.
Now, let's consider the scenarios you mentioned and determine whether addition or subtraction can be used:
1. When the coefficients of the x-terms or y-terms are the same:
- In this case, you can use addition or subtraction because the coefficients are the same. You can add or subtract the two equations to eliminate one variable.
2. When the negative values of the x-terms or y-terms are the same:
- Again, you can use addition or subtraction in this case because the negative values are the same. By adding or subtracting the equations, you can eliminate one variable.
3. When the negative values of the x-terms or y-terms are opposites:
- Here, you can also use addition or subtraction because the negative values are opposites. By combining the equations using addition or subtraction, you can eliminate the variable.
4. When the negative values of the x-terms or y-terms are fractions:
- Addition or subtraction can still be used in this case. You can add or subtract the equations as needed to eliminate the variable.
Therefore, your answer that "No addition or subtraction can be used when the negative value of the x-terms and y-terms are the same or opposites" is incorrect. Addition or subtraction can indeed be used in those scenarios.
I hope this explanation clarifies your understanding. If you have any further questions, please feel free to ask!
