Answer to Question 1

The formula showing how households can divide their income is Y = C + S + T, where Y is income, C is consumption expenditure and T is taxes. According to the expenditure approach income, GDP = C + I + G + X  M. But income, Y, equals GDP. So, setting the equalities equal to one another and removing C since it is on both sides gives I + G + X - M = S + T. Moving G, X and M to the right hand side gives the final result: I = S + (T - G) + (M - X). Here we see that investment is financed by private saving, S, government saving, (T - G), and borrowing from the rest of the world, (M - X).
