Answer 2

Answer:

Hey mate, Here's your answer ♤♡◇♧

Step-by-step explanation:

let the two digit number be

$10x + y$

it is Given that,

$x + y = 9$

And,

$x = \frac{1}{2} y$

So,

$= > x + y = 9$

$= > \frac{1}{2} y + y = 9$

$= > \frac{3y}{2} = 9$

$y = \frac{9 \times 2}{3}$

$y = 6$

$x = \frac{1}{2} y$

$x = 3$

then, The number is 36
