Hello here is your answer by Sujeet yaduvanshi


Solution:- Let to be 10'unit Digit Number be X

Let to be 1 unit digit number be y

then,

X+y=12

Again,

Original number=10x+y
Required Number=10y+x

then,

According to the question


10x+y+18=10y+x

10x-x-10y+y=-18

9x-9y=-18
9(x-y)=-18

x-y=-18/9

x-y=-2


THEN,

EQUATION HAS BEEN READY...
