You add both equations since -2x and 2x will cancel.
Becomes
5y=20
Y=4
Plug in y into equation
2x+2(4)=20
X=6

Answer:
(6,4)
Step-by-step explanation:
First we must cross out the -2x and 2x since they're both opposites of each other and thus they cancel each other out.
Now we have:
3y = 0
2y = 20
So next we add the 3 and 2 to get 5y, and then we add 20 and 0 to get 20.
So now we have:
5y = 20
And so we'll simply divide by 5 on both sides, and the answer is y = 4.
Now normally we would plug 4 back in to one of the equations to solve for x, but since only one of the answer choices has 4 in the y position, we can already tell that (6,4) is the answer.
Hope this helps you. Sorry if it doesn't though.
