8y = 4x -16
-x = -2y -4
Multiply all terms in the second equation by -1:
-x = -2y -4 x -1 = x = 2y +4
Now replace x in the first equation with this.
8y = 4(2y+4)
Simplify:
8y = 8y +16
Because there is an 8y on both sides of the equation, it cannot be solved.
The answer is no solution.
The answer is B, you should really learn how to calculate these yourself though because they come up a lot.
-9.5
I think I might be wrong
So,
In order to simplify a fraction, we have to factor both the numerator and the denominator.

Cross out ones.
