Please help me out!! I've been stuck on this for so long. I'm not sure if my algebra is off or what, but I need help!

Exercise 3 (Expenditure Minimization Problem) Suppese utility is given by U(.r,y) = a: - (1 + y), and the objectivefunction is given by page + pyy. a) Given the eenstraint that U03, 3;) = [7, derive the Hicksian demands fer a: and y, and the expenditure function. Use the Lagrangian Inethedte salve this preblenl. Note) To aveid any earner solution, we assume that [7 3: if.
