Question

GIVE THE ANSWER OF THE ABOVE PIC​

Answer 1

$solution$

Let the number in ten=10x

and in unit=y

$10x + y - 27 = x + 10y$

$10x - x = 10y - y + 27$

$9x = 9y - 27$

$9x = 9(y - 3)$

$x = y - 3$

$x + y = 15$

$x = 15 - y$

$15 - y = y - 3$

$2y = 18$

$y = 9$

$x + 9 = 15$

$x = 15 - 9$

$x = 6$

$(x,y)=(6,9)$
