Question

7n + 5 = 19 (n = 2)​

Answer 1

Step-by-step explanation:

7n + 5 =19

7*2 + 5 = 19

14 + 5= 19

19 = 19

hence proved

Answer 2

Answer:

=> $n=2$ is a solution of the given equation, $7 n+5=19$.

Step-by-step explanation:

Given that:-

$7 n+5=19(n=2)$

To check whether the value in the brackets is a solution to the given equation or not:

As we have,

=> $7 n+5=19(n=2)$

Putting the value of n as 2 in L.H.S.,

 

i.e 19 = 19

As L.H.S. = R.H.S.

Hence, satisfies the equation.
