  1. Answer:

    see this is your answer

    Step-by-step explanation:

    (a) Put n = 1 in the equation, we have :


    n + 5 = 15


    or 1 + 5 = 15


    or 6 \neq 15


    Thus n = 1 is not a solution.



    (b) Put n = – 2, we have :


    7n + 5 = 19


    or 7(-2) + 5 = – 14 + 5 = – 9 \neq 19.


    So, n = – 2 is not a solution to given equation.



    (c) Put n = 2, we have :


    7n + 5 = 19


    or 7(2) + 5 = 14 + 5 = 19 = R.H.S


    Thus n = 2 is the solution for the given equation.



    (d) Put p = 1 , we have :


    4p – 3 = 13


    or 4(1) – 3 = 1 \neq 13 .


    Thus p = 1 is not a solution.



    (e) Put p = – 4 , we get :


    4p – 3 = 13


    or 4(1) – 3 = 1 \neq 13 .


    Thus p = 1 is not a solution.



    (f) Put p = 0 , we get :


    4p – 3 = 13


    or 4(0) – 3 = – 3 \neq 13 .


    Thus p = 0 is not a solution.
