C.
<h2>
Why?</h2>
To find which of the given options are not the result of a substitution in the given system, we need to isolate the variable in function of the other variable, and then substitute it.
So, substituting and discarding, we have:
- First equation:
Isolating "y", we have:
Then, substituting it into the second equation, we have:
We have that it's a result of a substitutiong in the following system (option A)
- Second equation:
Isolating "y", we have:
Then, substituting it into the first equation, we have:
Have a nice day!
