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.
