Solve problem number 10. attached i also have an example of how to solve it (IB 2.1 Solving a problem by sooving its subproblems)

10. Using problem decomposition tree, solve the problem ?(x,y) (4x + y2 - 4y + 5 + 4x = 0) IB 2.1 Solving a problem by solving its subproblems Find x and y to satisfy t 9x + 25y2 + 6x 20y + 5 = 0. Solution: problem: ?(x,y) 9x2 + 25y? + 6x - 20y + 5 = 0. analysis: ?(x,y) (9x + 6x +19+(25y2 - 20y + 4) = 0 subproblems: ?(x)(3x + 1)* =0 ?(y) (5y-2)2 = 0 primproblems: ?(x) (3x + 1)=0 ?(y) Sy-2 = 0 solution x=-1/3 y = 2/5
