Answer:
<h2>Pilar is correct because both system of equations are satisfied by the same solution.</h2>
Step-by-step explanation:
To know if both systems have the same solutions we need to solve one of them, and then evaluate that solution with the other system.
Let's solve the first system
First, let's multiply the first equation by -2, then we sum both equations each other
Then, we use this value to find the other one
Therefore, the solution of the first system of equations is .
Now, let's evaluate this values in the second equation and see if they satisfy
They satisfy the first equation, let's evaluate the second one
They also satisfy the second equation. That means both system have the same solution.
Therefore, Pilar is correct because both system of equations are satisfied by the same solution.
