Question

Check whether the value given in the bracket is a solution to the given equation or not:

7n + 5 = 19 (n = 2)

Sum

Solution

7n + 5 = 19 (n = 2)

Putting n = 2 

L.H.S. = 7n + 5

= 7 × (2) + 5

= 14 + 5

= 19 = R.H.S.

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

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