Question

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)​

Answer 1

Answer:

( a.) n+5=19 ( n=1) is wrong×

Step-by-step explanation:

n=1

= 1+5=6 is not equal to 19

(b) n= -2

= 7( -2)+5=19

(c) n=2

= 7(2)+5= 19 is correct

(d) p= 1

= 4(1)-3=1 is not equal to 13

(e)p=-4

= 4(-4)-3= 19 not 13

(f) p=0

= 4(0)-3=-3 so it is wrong
