Answer 1

Answer:

32

Step-by-step explanation:

let the number be xy

so,

1. 10x+y=xy
2. x=3y
3. xy-36=yx

ft

, 2 in 1

10×3y+y=3y×y

30y+y=3y^2

31y=3y^2

31=3y

y=31/3

apply y in 2

x=3×31/3

x=31

xy= 10×31+31/3

= 310+31/3

= (930+31)/3

= 961/3

= 32.33

xy = 32

I think this may be the answer
