Answer 2

It seems like you're trying to perform a mathematical operation, but the expression you provided includes "94xy," which isn't a numerical value. If "xy" represents variables or unknown values, I can't perform the calculation without knowing the values of those variables.

Please provide the correct mathematical expression, or clarify the values of "x" and "y" so that I can help you calculate the result.
