then subtracting 5 or by multiplying the
difference of digits by 16 and adding 3.
Find the number.​

Answer 1

Step-by-step explanation:

let the no. be 10x+y

10x+y=8 (x+y)-5

10x+y=8x+8y-5

2x=7y-5....1

10x+y=16 (x-y)+3

10x+y=16x-16y+3

17y-3=6x....2

3 (7y-5)=17y-3

21y-15=17y-3

4y=12

y=3

2x=21-5

x=8
