hello here is your answer by Sujeet yaduvanshi ☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝☝
Let to be 10' unit digit=x
Let to be 1 unit digit=y
then,
X+y=10. ----(1)
Again,
10x+y+54=10y+x
10x-x+y-10y=-54
9x-9y=-54
9(x-y)=-54
x-y=-54/9
x-y=-6
Now solving the equation by elimination method:))
x+y=10
x-y=-6
_______
2y=16
y=16/2
y=8
then,
x+y=10
x+8=10
x=10-8
x=2
Again Required Number:).
10y+x
10*8+2
80+2
82
that's all
