1. The sum of the digits of a 2-digit number is 9. The number is 6 tim

1.	1. The sum of the digits of a 2-digit number is 9. The number is 6 times the units digit. Find the number.
Answer» => Let the digit in the units place = x => Let the digit in the tens place = y => Then the 2 digit number is = 10y + x => x + y = 9............( 1 ) => The number is 6 times the units digit. So, => 10y + x = 6x => 10y = 5X => 2Y = x..........( 2 ) => Substitute x = 2y in equation ( 1 ) => 2y + y = 9 => 3Y = 9 => y = 3 => x = 2y => x = 2 × 3 = 6 => Now, the number is = 10y + x => 30 + 6 => 36 I hope this will HELP you dear.. ALWAYS stay safe and stay healthy..

1. The sum of the digits of a 2-digit number is 9. The number is 6 times the units digit. Find the number.

Answer»

=> Let the digit in the units place = x

=> Let the digit in the tens place = y

=> Then the 2 digit number is = 10y + x

=> x + y = 9............( 1 )

=> The number is 6 times the units digit.

So,

=> 10y + x = 6x

=> 10y = 5X

=> 2Y = x..........( 2 )

=> Substitute x = 2y in equation ( 1 )

=> 2y + y = 9

=> 3Y = 9

=> y = 3

=> x = 2y

=> x = 2 × 3 = 6

=> Now, the number is = 10y + x

=> 30 + 6

=> 36

I hope this will HELP you dear..
