Check whether the value given in the brackets is a solution to the given equation or no

Question

(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

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

putting p =1 in L.H.*.,

4(1) - 3 = 4-3 = 1

since LHS =1 ≠R.H.*

Therefore p =1 is not the solution of given equation.
