I have a function: [tex]f(x,y)=x^3+y^3-3x-12y+20[/tex]

Given that I know a value of x, ie [tex]x=-1[/tex], how do I extract a value of y using this notation?

I know when [tex]f(x)=x^2[/tex] I can use substitute [tex]f(x)[/tex] with [tex]y[/tex], but I find myself stuck with what to substitute [tex]f(x,y)[/tex] with...
