Question

Solve the following equation by trial and error method 6n=30

Answer 1

Answer:

Taking n value as 1=

6(1)= 30

6 ≠ 30

Therefore 1 cannot be the answer.

Taking n value as 2=

6(2) = 30

12 ≠ 30

Therefore 2 cannot be the answer.

Taking n value as 3=

6(3) = 30

18 ≠ 30

Therefore 3 cannot be the answer.

Taking n value as 4 =

6(4) = 30

24 ≠ 30

Therefore 4 cannot be the answer.

Taking n value as 5 =

6(5) = 30

30 = 30

Therefore 5 is the answer.
