Question

The sum of two number is 11 and their difference is 5 find the number.

Answer 1

Answer:

Let one of the number be x.

Then other number will be x - 5.

As per given condition

$x + x - 5 = 11 \\ \\ 2x - 5 = 11 \\ \\ 2x = 11 + 5 \\ \\ 2x = 16 \\ \\ x = \frac{16}{2} \\ \\ x = 8$

So the numbers are

x = 8

And

x - 5 = 8 - 5

= 3
