Answer:

Check whether the value given in the brackets is a solution to the given equation

or not:

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

(b) 7n + 5 = 19 (n = – 2)

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

(d) 4p – 3 = 13 (p = 1)

(e) 4p – 3 = 13 (p = – 4)

(f) 4p – 3 = 13 (p = 0)

Solution 2 :

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

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

= n+5 = 19

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

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

-14+5\ =\ 19\−14+5 = 19

9\ne199

=19

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

7\times2+5=19\7×2+5=19

14+5\ =\ 19\14+5 = 19

19=1919=19

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

4\times1-3=13\4×1−3=13

4-3=134−3=13

1\ne13\1

=13

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

4\left(-4\right)\ -3\ =\ 134(−4) −3 = 13

-16\ -3\ =\ 13\−16 −3 = 13

-19\ \ne13−19

=13

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

4\times0\ -3=134×0 −3=13

0-3=130−3=13

-3\ne13−3

=13
