HELP! 2 problems!
Anit [1.1K]

Answer:

 x=4   (solution)                             x=-14             (extraneous solution )

Step-by-step explanation:

|x+5|=9 -------original equation

Equation can be equal to +9   and -9

x+5 =9                           x+5 =-9

x= 9-5                            x=-9-5

 x=4   (solution)                             x=-14             (extraneous solution )

                                       

for checking  

x+5 = 9                                            x + 5=9

4+5= 9                                             -14+5=9

9=9                                                    -9=-9
