  2. Answer:

    The sum of the 2 digit number is 9. The number is 6 times the units digit. Find the number.

    Answer:-

    Let x be the digit at the ten’s place then (9 – x) will be the digit at the unit place.

    → the two digit number = 10x + 9 – x = 9x + 9

    According to the conditions in the questions, we get

    9x + 9 = 6(9 – x)

    → 9x + 9 = 54 – 6x

    → 15x = 45

    → x = 3 …. digit at the ten’s place

    9 – x = 9 – 3 = 3 …digit at the unit place

    → the two digit number = 9x + 9 = 9(3) + 9 = 36
