Question

sum of two no is 97 and their difference is 3 find number​

Answer 1

Answer:

Let the numbers be x and y.

Therefore,

x+y=97

x-y=3

Therefore, x=97-y

Therefore,97-y-y=3

or, y=47

Therefore,

x+47=97

or, x=50

Answer 2

$let \: \: 2 \: \: \: no \: \: \: be \: \: \: \: x \: \: \: \: nd \: \: \: \: y \\ \\ x + y = 97 \\ x - y = 3 \: \\ ...................... \\ 2x = 100 \\ \\ x = 50 \\ \\ x - y = 3 \\ \\ 50 - y = 3 \\ \\ y = 47$
