Calculate the compensating variation hint at the new price

Question

Consider a consumer whose preferences can be represented by the utility function

u(x, y) = x + y

1. Originally, px = 1, py = 2 and m = 1. What bundle does the consumer choose, and what is his utility from this bundle?
2. The price of good x then rises to 3. What bundle does the consumer choose after the price change, and what is his utility from this bundle?
3. Calculate the compensating variation. (Hint: at the new price ratio, what good will he spend his income on?)
4. Calculate the equivalent variation.
