Question

1) The sum of the digits of a two-digit number is 15 and the difference between the digits is 3. What is the two-digit number?

Answer 1

Answer:

pls mark the answer brainlest........

Step-by-step explanation:

Let the first digit be x, and the second one be y, then

x + y = 15 ———-(1)

x - y = 3 ———-(2)

Adding (2) and (1), we get

2x = 18

So, x = 9.

Putting the value of x in (1), we get

9 + y = 15

Therefore, y = 6.

So, the two digit number is ‘96’.

Answer 2

Answer:

cannot be determined

Step-by-step explanation:

Let the ten's digit be x and unit's digit be y.

Then, x + y = 15 and x - y = 3 or y - x = 3.

Solving x + y = 15 and x - y = 3, we get: x = 9, y = 6.

Solving x + y = 15 and y - x = 3, we get: x = 6, y = 9.

So, the number is either 96 or 69.

Hence, the number cannot be determined
