Step-by-step explanation: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
