Let the no be 10y+x
atq
10y+x=5 (x+y )
9y=4x
y=4x/9 .......................(i)
 part 2
10y+x=2xy+5 
from i
 i hope now u can do it

This is the continuation
from i.........
10*4x/9+x=2x*4x/9+5
if we calculate the value we get
8x²-49x+45=0
split -49x into -40x-9x
we get (8x-9)*(x-5)=0
∴x=9/8 or x=5
∵x should be a digit we consider
x=5
we got 10y+x=2xy+5 from this calculate
the answer ..............this really helps you mark as brainliest if you think it helped you.

but we havw to fin x
ok thats too good x=5
