It appears that all they want you to do is to distribute the negative sign through the second parentheses and combine like terms. It would turn into:

x +  3y - 5Z - x + 2y - 6Z

Combine all the x's, all the y's and all the z's, and write the expression: 

5Y - 11Z

Isn't that cool the way that the opposite signs on the x's make them disappear?

This is not an equation - there's no equal sign, right?  We can't actually solve to get values for the variables. Is that what was confusing you?

By the order of operations, multiplication comes before addition. The (x-2y+6z) is being mulitplied by -1, so distribute that through first. Then remember that addition is commutative and you can add/subtract like terms together, for example  3y + 4y = 7y.
