Answer 2

Answer:

35 please mark me as brianliest

Step-by-step explanation:

So , given number =10(8−x)+x

                                =80−10x+x

                             =80−9x

Now if digits are reversed  , then Number obtained  

                                =10x+(8−x)

                                =10x+8−x

                                =9x+8

According to question

       (80−9x)+18=9x+8

        98−9x=9x+8

        90=18x

          x=5

⇒ given number  =80−9x

                                         =80−9×5      

                                         =80−45

                                         =35
