Question

I'll mark as brainliest pls tell it's urgent.​

Answer 1

Answer:

22 because here we have to find the two digit number

Answer 2

       $\underline{\bold{Answer:}}$

       $36$

       $\underline{\bold{Step-by-step-explaination:}}$

       $\text{Let the one's digit of the number by }y \text{ and the ten's digit be }x$

$\implies \text{The number is }(10x + y)$        

       $\text{According to the question:}$

$\implies \boxed{x+y = 9} \text{ ------(i)}$

       $\text{The question also states that:}$

       $\boxed{10y + x = 10x + y + 27}$

       $\text{Transposing the terms from R.H.S to L.H.S}$

$\implies \boxed{10y + x - 10x - y - 27 = 0}$

       $\text{Simplifying the equation}$

$\implies \boxed{9y - 9x - 27 = 0}$

       $\text{Taking 9 common}$

$\implies \boxed{y-x - 3 = 0} \text{ ------(ii)}$

       $\text{Adding (i) and (ii)}$

$\implies \boxed{x + y + y - x - 3 = 9}$

       $\text{Simplifying the equation}$

$\implies \boxed{2y - 3 = 9}$

       $\text{Transposing 3 to R.H.S and simplifying the equation}$

$\implies \boxed{2y = 12}$

       $\text{Transposing 2 to R.H.S}$

$\implies \boxed{y = \frac{12}{2} = 6}$

       $\text{Now substituting the value of }y \text{ in (i)}$

$\implies \boxed{x+6 = 9}$

       $\text{Transposing 6 to R.H.S and simplifying the equation}$

$\implies \boxed{x = 3}$

   $\therefore \text{ }\text{The number}= 10x + y = 10(3) + 6 = 36$
