Question

(a) n + 5 = 19(n = 1)​

Answer 1

Answer:

Therefore this sum is solve at two methods

First method n+5=19 ( n=1)

n = 19 - 5

n = 14

therefore n =1 is not correct

Second method n+5=19 (n=1)

L.H.S. = n+5×1

= n = 5

R.H.S. = 19 × 1

= 19

Therefore n=1 is not correct

Answers is same but methods is difference
