12．For example, the price of commodity 1 decreases with the price of commodity 2 fixed, we can draw a line with the same slope of the new budget line through the initial consumption bundle. And it is easy to find
that any bundles lying on the left side of the new line are less than the initial consumption of x1 and vice versa. If the substitute effects are positive, we will find that the new optimal point lying on the left
