Step-by-step explanation:
Not sure what you mean by the second half, but I'll answer the first question. Since the number is two digits, you can represent it as 10x + y. If you reverse the digits, it becomes 10y + x. So, 11x + 11y = 143, and 9x - 9y = 9. Solving for x and y, you find x = 7 and y = 6.
