Check whether the value given in the brackets is a solution to the given equation or not: (a) `n+5=19(n=1)` (b) `7n+5=19(n=-2)` (c) `7n+5=19(n=2)` (d) `4p-3=13(p=1)` (e) `4p-3=13(p=4)` (f) `4p-3=13(p=0)`

Explanation

(a) `n+5 = 19`

For `n = 1`,

`1+5 = 19=> 6 = 19`, which is not true.

So, `n=1` is not a solution.



(b)`7n+5 = 19`

For ` n = -2`

`7(-2)+5 = 19=> -9 = 19`, which is not true.
