Answer: third option
Step-by-step explanation:
There are 2 ways to go about systems of equations normally, and that's elimination and substitution. For this particular problem, I would recommend elimination.
we see the first equation 4x+2y=4
we want to be able to simplify it as much as possible (so it's easier to solve)
so we divide all the terms by 2, giving 2x+y=2.
the second equation can't be simplified, so we set up the elimination method.
2x+y=2
-3x-y=-7
multiplying both equations by 2 and 3, we subtract them and get that y equals 4, which is clearly the answer.
