The sum of the digits of a two digit number is 9. if 27 is subtracted from the
number the digits interchange their places. find the number.
pls answer fast

The number is 63.

Step-by-sep explanation:

Let the 2 digits be x and y where the number is xy.

x + y = 9(1)

Also if we subtract 27:

10x+y  - 27 = 10y + x

9x  - 9y = 27      Divide this through by 9:

x - y = 3 (2)

Adding equations  (1) and (2):

2x = 12

x = 6.

Substituting in (1):

6 + y = 9

y = 3.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
