Question

Sum of the digits of a 2-digit number is 9. When the digits are reversed, it is found that the resulting number is greater then the original number by 45 pls do in linear equations with one variable

Answer 1

Answer:

18

Step-by-step explanation:

let once position be x

tens position = 9 - x

so,

90 - 10x

if , we reverse this number

We get

10x + 9 - x

so lets solve this

10x + 9 - x = 90 - 10x + x +45

9x + 9 = -9x+ 135

9x + 9x = 144

18x = 144

x = 144/18

= 8

So, One's Position = 8

and ten's Position = 9-8 = 1

So the number is 18
