D. x = 0
Step-by-step explanation:
The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute in the formula


therefore
The solutions are x=0 and x=9
You have to set up a system of equations
x+y=104
3x-y=104
Sodas = 78
Hotdogs = 26
If you could write out the whole problem exactly how it is, I can solve it for you.
