Answer 1

Explanation:

A two digit positive integer can be written as 10x+y, where x is the ten's digit and y is the one's digit.

For example, 52 = 10(5)+2

So, if we let x = ten's digit and y = one's digit, then:

x+y=11

(10x+y)+45 = 10y+x

Simplify to get x+y = 11

9x-9y = -45

Dividing the second equation by 9, we have x+y = 11

x -y = -5

Add the equations to obtain 2x = 6. So, x = 3

Since x+y=11 and x=3, y = 8.

The number is 38.
