Step-by-step explanation:

Let the tens digit be x

Let the unit digit be y

Sum of two digit is 14

So,$x+y = 14$ --A

Now w are given that twice the tens digit exceeds the units digit by one

So,$2x-y=1$

Substitute the value of y from A

$2x-(14-x)=1\\2x-14+x=1\\3x-14=1\\3x=15\\x=5$

Substitute the value of x in A

5+y=14

y=9

Hence The tens digit is 5 and unit digit is 9
