Question

I WANT SOLUTION AND EXPLANATION ANSWER IS GIVEN AT LAST!!!

Answer 1

Answer:

• 94

Step-by-step explanation:

Let the 2-digit number is ab, then its reverse is ba.

We have:

• ab - ba = 45  -------> (1)

and

• a + b = 13 -------> (2)

The first equation is simplified considering ab = 10a + b, ba = 10b + a

• 10a + b - 10b - a = 45
• 9a - 9b = 45
• a - b = 5  -------> (3)

Now add up the first and third equations:

• a + b + a - b = 13 + 5
• 2a = 18
• a = 9

Find the value of b:

• b = a - 5 = 9 - 5 = 4

The number is 94, your answer is considering the reverse number.
