Yes, for every value of x, there is only one value of y. This means that y is a function of x.
The answer is:
4x+2y=11} 4x+2y=11} x=2-2y
x-2=-2y } x+2y=2 } x=2-2(-3/6)
x=2-(-6/6)
4(2-2y)+2y=11 x=2-(-1)
8-8y+2y=11 x=3
8-6y=11
-6y=11-8
-6y=3/-6
y=-3/6=-1/2
So for my opinion the solution is A.(3,-1/2)
(16xy + xy) + (4x) + (3y) + (-13 + 21)
17xy + 4x + 3y + 8
