Question

A number consists of two digits whose sum is 9. If 27 is subtracted from the number its

digits are reversed. Find the number.​

Answer 1

Answer:

63

Step-by-step explanation:

first digit=x; second digit=y

then we have first equation x+y=9 (1);

the number is in the form of 10x+y and when the digits are reversed so it is in the form 10y+x

so we have 10x+y-27=10y+x =>9x-9y=27 (2) We have the second equation

from (1) and (2) we have x=6 and y=3

6+3=9 and 63-27=36

Answer 2

Answer:

Step-by-step explanation:

that number is 63 and 36

Because

By First condition

6+3=9

Second condition

63-36=27
