Write out the equations ∆Y and ∆X

[Kinetica]

Homework Statement

If I am given a couple of equations asking to write out the equations for which ∆Y_t=∆X_t=0:

∆Y_t=–0.5(Y_t–Y*)+0.3(X_t–X*)
∆X_t=0.4(Y_t–Y*)–0.3(X_t–X*)

It is also known that Y_t and X_t are endogenous and Y* and X* are steady-state values (if this helps).

Any hints on how to proceed?

I started with this:
–0.5(Y_t–Y*)+0.3(X_t–X*) = 0
0.4(Y_t–Y*)–0.3(X_t–X*) = 0

I just don't know what to do with extra Y* and X*. Any help is greatly appreciated.
