There are three independent variables given that f(x,y,z) = xz + ylnx + x^2 + 4 how do you intent to define x and function of independent variable 'x' and 'y'

i got headache with this too ><

apparently you can put f(x,y,z) = some constant ... sill separating x from those values is quite difficult

ooop i forgot xz + ylnx + x^2+ 4 = 0

still separating x out of ln(x) is quite a challenge. while you can do the last part

how can i separate x from lnx do you have any concept to do that?

the last part requires that ... for separation of x, PDE is the best guess,

about find the value in the last part i know how to solve it, but about define x as differentiable function of two independent variable y and z i still not clear
