Correct option is the second option .
Answer: SECOND OPTION
Step-by-step explanation:
You can solve the system of equations by the method of substitution:
- You must susbtitute the second equation into the first equation and solve or x:

- Now, you must susbtitute the value of x obtained above into the second equation to calculate the value of y. Then, you have:

Therefore, you obtain:
