Consider the following system; X1 +x2 + 3x3 – 2x4 = 0 2x, + 3x2 + 7xз — 2х4 %3D 9 Зх, + 5x, + 13х3- 9х4 %3D 1 Find all possible combination of endogenous variables. (Hint: Check whether (x1, X2, X3) can be endogenous variables and x4 can be exogenous variable for this system. And then, check all other combinations.)
