Answer:
<h2>System 1 and System 2 are equivalent.</h2>
Step-by-step explanation:
The first and second system have the same solutions, the are equivalent systems of equations. Let's calculate solutions to demonstrate it:
<h3>System 1.</h3>
If we multiply the second equations by -5, we can eliminate one variable and find the first solution:
Now, we use this value to find the other solution:
The solution of the first system is
<h3>System 2.</h3>
We do the same process than we did before, but this time we have to multiply by :
Then,
The solution of the second system is
Therefore, system 1 and system 2 are equivalent.
