<h2>Hello!</h2>
The answer is:
The only operations that could be used to solve the system using addition are the first and the third operation.
<h2>Why?</h2>To solve the problem, we need to check and discard each of the given option to see if the operations works to solve the system using addition, so, trying the given options.
The system of equation is:
We can see that the only way to solve the system using addition, is multiplying the first or the second equation by -1, so, we can eliminate the variable "y", let's prove that:
- First operation: Multiplying<u> the first equation</u> by -1 and add the equations together,
Adding the equations, we have:
We can see that we can solve the problem using the first operation the operation.
- Third operation: Multiplying <u>the second equation</u> by -1 and add the equations together,
Adding the equations we have:
We can see that we can solve the problem using the third operation.
Also, we can see that in both equations the variable "y" has the same coefficient, the only operations that could work to solve the system using addition are the first and the third operation.
Have a nice day!
