Problems on proving given functions again

I really need help on this.

Show that each of the following functions satisfy the given relative function that includes partial differentiation.

1. differentiate z w.r.t x and then w.r t. y and compare f'(ax+by)... you will get the ans.
2. differentiate z w.r.t x and then w.r t. y and then compare then solve for LHS and whenever there is x^n*f(y/x), substitute z for it.
