x and y
according to question
x+y=14
x+y-14=0..................... (1)
here
the assumption number be 10x+y
x is tenth digit
and
y is unit' digit
so
atq
10x+y+18=10y+x
9x-9y+18=0
x-y+2=0.................... (2)
adding equations (1) +(2)
x+y-14+x-y+2=0
2x-12=0
x=12/2
x=6
substitute
x in equation (1)
6+y-14=0
y=8
therefore the number is
68.
