## econometrics - multipliers

hello all, I have a problem with such an econometric exercise: the task is to compute impact, interim and long-term multipliers for the following two- equations model:

$y_{1t} = 2 + 0,6x_{1t} + 0,3x_{2,t-1} +0,1y_{1,t-1} - 0,05y_{2,t-2}$
$y_{2t} = 3 + 0,2x_{1t} + 0,8x_{2,t-1} +0,2y_{1,t-1} + 0,1y_{2,t-2}$

the problem here is that we have two lags (t-1, t-2) of endogenous variable... Can someone help ?
