This is what I’ve got so far: 1. dxe^y + dyxe^y + dyf(z) + yf’(z)dz = 0 2. g(x,y) + x(dg(x,y)/dx)dx + x(dg(x,y)/dy)dy = -2zdz

Consider the equation system x*e^y + y*f(z) = a x*g(x,y) +z^2 = b where f(z) and g(x,y) are differentiable functions, and a and b are constants. Suppose that the system defines x and y as differentiable functions of z. Find expressions for dx/dz and dy/dz. Any help would be appreciated...
