If x, y, and z are integers greater than 1, and (327)(510)(z) = (58)(914)(xy), then what is the value of x?

(1) y is prime
(2) x is prime
statement (1) alone is sufficient, but statement (2) alone is not sufficient.
statement (2) alone is sufficient, but statement (1) alone is not sufficient.
both statements together are sufficient, but neither one alone is sufficient.
each statement alone is sufficient.
statements (1) and (2) together are not sufficient.

Statements (1) and (2) TOGETHER are NOT sufficient.

Explanation:

As in the equation (327)(510)(z) = (58)(914)(xy) there are THREE variables in total i.e. "x", "y" and "z" hence minimum three equations are required to find out values of all variables. Hence,

If the given number of equations is equal to total variable used in any of the equation, values of all the variables can be find out otherwise there can be unlimited number of solutions.

So, value of "x" cannot be determined with the given data.

i believe it is c.y = 9x
