Question

solution of that answer what the number

Answer 1

X + X is equals to 9
X+X-27= 9
X+X=9+27
2X= 36
X=36÷2=18

Answer 2

HEY BUDDY!
THERE THE SOLUTION-------
Let the unit's digit be x & the ten's digit be y
It's given that x+y=9 ----------(i)
So, the no. is 10x+y
If 27 is subtracted from the number,it's digits are reversed.
So,
10x+y-27=10y+x
9x-9y=27
x-y=3 ------------(ii)
Adding (i) & (ii)
2x=12
x=6
Therefore,
y=9-x
y=9-6
y=3

The no.=10x+y
= 10(6)+3
= 60+3
=63
