Implicit Differentation with 2 equations (each with 2 variables and 1 parameter)

3) For the system of equations below, check whether the two conditions in the Implicit Function Theorem are satisfied at point A = (x, y, t) = (1, 1, 0), where x and y are variables and t is a parameter. If yes, find the expression for the partial derivative of x with respect to t, and evaluate it at A.

. . . . .xy2 - y = 5t . . . . .2yt = x3 - 1


Pretty stuck on this one guys, i couldnt find much in my notes or online. Im thinking i may have to use Jacobian however?

There seem to be many lessons, explanations, and examples online, such as here, here, and here.

Where, specifically, are you getting stuck? Thank you! ;)
