Answer 1

Answer:

(a) n+5 = 19 (n=1)

1+5\ =\ 4\ \ne\ n+5\ =\ 19\

(b) 7n+5 = 19 (n=-2)

7\times\left(-2\right)\ +\ 5\ =\ 19\

-14+5\ =\ 19\

9\ne19

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

7\times2+5=19\

14+5\ =\ 19\

19=19

(d) 4p-3 = 13 (p=1)

4\times1-3=13\

4-3=13

1\ne13\

(e) 4p-3 = 13 (p=-4)

4\left(-4\right)\ -3\ =\ 13

-16\ -3\ =\ 13\

-19\ \ne13

(f) 4p-3 = 13 (p=0)

4\times0\ -3=13

0-3=13

-3\ne13
