Step-by-step explanation:

Let ten digit be x

unit digit be y

so the equation is (x - y = 5)

Number= 10x +y

Reverse number = 10y+x

8(10x + y) = 3(10y + x)

80x 8y = 3y + 3x

77x = 22 y

7x - 2y =0

now,,

x-y = 5 multiply 2

7x - 2y=0 equation (2)

2x-2y=0

-7x + 2y = 0

-5x = 10

x = -2

Therefore,,,,

-1-y = 5

-y = 7

y = -7

Number = 10x + y

2*10*7 = 27
