To solve the system of equations using the comparison method, we need to manipulate the equations so that we can compare them directly.Given the system of equations:
We can subtract the first equation from the second equation to eliminate
:
Now, we can substitute the value of
into the first equation to find
:
So, the solution to the system of equations is
and
.Now, let's analyze the given options:
The correct equation that could be the result of using the comparison method to solve the system is
.
