Final answer:
To solve the system of equations, we need a second equation to form a solvable system.
Step-by-step explanation:
To find the solution (x, y) to the system of equations yy == -64x + 12, we need more information. The given equation is not sufficient to solve for two variables. We need another equation to form a system that can be solved. Once we have a second equation, we can use algebraic methods such as substitution or elimination to find the values of x and y.
