Having some basic problems with economic equations: Y =0.5Y + 200 +I becomes: Y = (200+I)/0.5 Can anyone show me the steps to get from the first to the second? many thanks, Simon

$y = 0.5y + 200 + I$ $y  0.5y = 200 + I$ $y(10.5) = 200+I$ $y(0.5) = 200+I$ $y = \dfrac{200+I}{0.5} = 2(200+I)$

many thanks for the help I always seem to fall down on the fact that : Y  0.5Y can be factored into y(10.5) . The last equation I posted which you kindly solved for me had the same conceptual step. Maybe it will sink in one day
