This is false. the answer should be x+5
<span>Let
x = the 10s digit
y = the units
N1----------> original number
</span>N2----------> new number
<span>N2=N1+36--------- >N2-N1=36
y+x=8------------- > equation (I)
then
10x + y = N1
10y+x=N2
(10y+x)-(10x+y)=36- -----> 9y-9x=36------- > y-x=4----------- > equation (II)
resolving (I) and (II)
</span> y+x=8
y- x=4<span>
-----------------
2y+0x=12--------------- >y=6
then
x=8-y=8-6=2----------> x=2
N1=26 and N2=62
the two digit number is 26</span>
