Answer 2

Answer:

answer-82 hope it helps

Step-by-step explanation:

The number is 82.

82 - 54 = 28

Let x = digit in 10’s column and let y = digit in 1’s column

Therefore: x = 4y and (10x + y) - 54 = 10y + x

Substitute x = 4y

10 (4y) + y -54 = 10y + 4y

Solve for y yields y = 2

Therefore x = 8

The number is 82.
