Question
Check whether the value given in the bracket is a solution to the given equation or not.
$n + 5 = 19 (n = 1)$
✓

Answer

$n + 5 = 19 (n = 1)$
$L.H.S. = n + 5 = 1 + 5 = 6 .. . .$ [ When $n = 1]$
$R.H.S. = 19$
$\because L.H.S. \neq R.H.S.$
$\therefore n = 1$ is not a solution to the given equation $n + 5 = 19.$
