2x+2x+4y-4y=16+0
4x=16
x=16/4
x=4
2(4)+4y=16
8+4y=16
4y=16-8
4y=8
y=8/4
y=2
2(4)-4(2)=0
Tada answer is A.(4,2)
4x=16
x=16/4
x=4
2(4)+4y=16
8+4y=16
4y=16-8
4y=8
y=8/4
y=2
2(4)-4(2)=0
Tada answer is A.(4,2)

The answer is A. Put the two equations together and you get 4x=16, so x=4. plug that back in so 2(4)-4y=0 and you get y=2
