Question

A two-digit number is 3 more than 4 times the sum of its digits. If 18 is added to the
number. Its digits are reversed. Find the number​

Answer 1

Answer:

Let the tens and the units digits be x and y

Number = (10x+y)

According to the question

=> 10x + y = 4(x+y) + 3

=> 10x + y = 4x + 4y + 3

=> 10x - 4x + y - 4y = 3

=> 6x - 3y = 3

=> 2x - y = 1 .........(1)
