Question
Check whether the value given in the bracket is a solution to the given equation or not.
$7n + 5 = 19 (n = –2)$
$7n + 5 = 19 (n = –2)$
✓
Answer
$7n + 5 = 19 (n = –2)$
$L.H.S. = 7n + 5$
$= 7 (–2) + 5 . . . . [$ When $n = –2]$
$= –14 + 5$
$= –9$
$R.H.S. = 19$
$\because L.H.S. \neq R.H.S.$
$\therefore n = –2$ is not a solution to the given equation $7n + 5 = 19.$
$L.H.S. = 7n + 5$
$= 7 (–2) + 5 . . . . [$ When $n = –2]$
$= –14 + 5$
$= –9$
$R.H.S. = 19$
$\because L.H.S. \neq R.H.S.$
$\therefore n = –2$ is not a solution to the given equation $7n + 5 = 19.$
