Question

the sum of the digit of a two digit number is 12 if the new number formed by reversing the digit is greater than the original number by 54 find the original number check your solution​

Answer 1

Step-by-step explanation:

original number = 10x+y

reversing number = 10y+x

y+x=12

10y+x= 10x+y+54

9y-9x=54

y-x=6

y+x=12

y-x=6

subtract

2x=6

x=3, y =9

number =39

reversing number =93

93-39=54
