how
sorry, it is 64.let the two numbers be x and y. x+y=10, 10x+y-18=10y+x,9x-9y=18, x-y=2,then x=6,y=4, there fore the number is 64
sorry what ever the explanation is given is also not correct
let the numbers be x and y. x +y=10, 10x+y-18=10x-20+y+2=10(x-2)+y+2. this number has equal digits. hence x-2=y+2 therefore x-y=4.on solving we get x =7,y=3. therefore the number is 73
73
