Answer: D. Two or zero
Step-by-step explanation: x=-7/6+-1/6√385
There isn't an exact place you could really solve this number, regardless of the way you break it down
The sum of the left side of these two equations is equal to the same of the right side is these two equations
4x+8y + (-4x+2y) = 20 + 30
10y =50 ( x is eliminated)
y=5
Take this into the second equation
-4x +2y = 30
-4x + 2*5 = 30
x=-5
So x=-5
y=5
