Question

w+y=z/x and xw+xy=z
solve for x

Answer 1

not enough info .-.

Answer 2

w+y=z/x and xw+xy=z These two equations are identical. Check this out.
You can't solve specifically for x without having values for w, y and z, but you can write x interms of w, y and z. In other words, your solution will be an algebraic formula without numeric values.

Answer 3

They are identical and you can tell they are identical because if on the equation on the left you multiplied the x onto both sides
x(w+y) = zx/x
you would be left with the equation on the right
xw+xy = z
