Answer 1

Answer:

Step-by-step explanation:

Solution to equation means by applying the given value of n or p in equation, the value on both sides of equation must be equal.

1)  n+5=19  ;  n=1

   Substituting n with 1 in the equation,

   1+5=19

   6 = 19   This is not possible

So, n=1 is not a solution to the equation.

2)  7n+5=19   ; n=(-2)

   7(-2)+5=19

   (-14)+5=19

   (-9) =  19

No, n=(-2) is not the solution.

3)  7n+5=19  ; n=2

    7(2)+5=19

    14+5=19

    19=19

Yes, n=2 is a solution to the equatin.

4) 4p-3=13  ; p=(-4)

   4(-4) -3=13

   (-16) -3 = 13

   (-19) = 13

No, p=(-4) is not a solution.

5) 4p - 3 = 19  ;p=0

   4(0) - 3 = 19

   0 - 3 = 19

   (-3) = 19

No, p=0 is not a solution.
