Sqrt(x+2)=sqrt(3-x) решить , а то мне два поставят

ответ: 

                                  ОДЗ: 1) x + 2 ≥ 0
x + 2 = 3 - x                                                                      x ≥ - 2
2x = 1                                                                            2) 3 - x ≥ 0
x = 0,5                                                                               - x ≥ - 3
                                                                                           x ≤ 3
                                                                                           x ∈ [- 2 ; 3]
ответ: 0,5
