35+18=53
53-18=35
a+b=8
ab+18= ba
a=3

HERE IS YOUR ANSWER:
STEP BY STEP EXPLANATION:
Let the ten's digit of the number be x and one's digit of the number be y.
Since the number is 2 digit is can be weitten as 10x+y
According to the question
x+y=8
so, x=8/y----(1)
Now when number is reversed , the new number will be 10y+x
Now, 10x+y+18=10y+x
10x-x+18=10y-y
9x+18=9y
9(x+2)=9(y)
x+2=y
putting the value of x from (1)
we get, 8/y+2=y
8+2y/y=y
8+2y=y^2
0=y^2-2y-8
0=y^2-4y+2y-8
0=y(y-4)+2(y-4)
0=(y-4)(y+2)
so, y=4 , -2
digit cannot be negative so, y=4
now, x=8/y=8/4=2
Hence, the number is 24
