I tried to follow https://economics.stackexchange.com/questions/16744/how-to-derive-utility-function-from-indirect-utility-in-this-exercise, but the problem is that one of the goods in this case has normalised price.

Why is $x_2$ occuring in the expression of the demand function for $x_1$? The price should be denoted $p$ or $p_1$ but not both.

Turns out I mistook a constant as a good because it used the same letter as I have used in other expressions to represent as a good.

What is the typical utility function of this demand function?

$$x\_1 = \ln(x\_2) - \beta \ln(p\_1) + \gamma \ln(y).$$

With budget constraint $y = p x\_1 + x\_2.$
