Question

Solve the following equation by trail and error method 3m-14=4

Answer 1

Answer:

(i) 3(1)-14=4

3-14=4

-11 is not equal to 4

(ii)3(2)-14=4

6-14=4

-8 is not equal to 4

(iii) 3(3)-14=4

9-14=4

-5 is not equal to 4

(iv) 3(4)-14=4

12-14=4

-2 is not equal to 4

v)3(5)-14=4

15-14=4

1 is not equal to 4

vi) 3(6)-14=4

18-14=4

4=4

therefore m=4

Answer 2

3m-14=4

putting m=4

(3×4)-14=2 not equal to R.H.S

putting m=5

(3×5)-14=1 not equal to R.H.S

putting m=6

(3×6)-14=18-4=4 it is equal to R.H.S

Hence m=6 is the solution of the question
