ab are bara deasupra
ba are bara deasupra​

Answer 1

$\it (\overline{ab}+\overline{ba}):(a+b)=x-2016 \Rightarrow (10a+b+10b+a):(a+b)=x-2016 \Rightarrow \\ \\ \Rightarrow (11a+11b):(a+b)=x-2016 \Rightarrow 11(a+b):(a+b)=x-2016 \Rightarrow\\ \\ \Rightarrow 11=x-2016 \Rightarrow x=2016+11 \Rightarrow x=2027$
