X + Y = 9 (i) equation
and (10x+y)/y =6
= 10x +y = 6y
= 10x = 5y
=y = 10x/5
putting the value of y in first equation we get
x + 10x/5 = 9
= 5x + 10x = 9*5
= 15x = 45
= x= 45/15 = 5
X = 5
Y = 9-5 = 4
i am in 9 standard if there is any mistake then sorry .

Answer:
36
Step-by-step explanation:
Give the number is ab = 10a+b
a+b = 9 -------(1)
(10a+b)/b = 6--(2)
(2) :
10a +b = 6b
10a = 5b
a = 2b
(1) :
a + 2a = 9
3a = 9
a = 3
so b= 2*3 = 6
The number is 36
