Answer 3

It seems like the equations you provided are incomplete. They don't have all the necessary information for me to solve for the variables. The equations should have a variable (X or Y) on the left-hand side and a constant on the right-hand side for us to find the value of the variable.

To solve these equations, please make sure they are complete with all the necessary information, and I'd be happy to help you find the values of X and Y.
