Answer 2

Answer:

41

Step-by-step explanation:

let the units place be y and the tens place be x

so, 4y=x---->(1)

10x+y+10y+x=55

11x+11y=55

dividing the equation by 11, we get,

x+y=5---->(2)

substituting (1) in (2)

4y+y=5

5y=5

y=1

substituting the value of y in (1),

x=4*1

x=4

therefore the number is 41
