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»

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)
