Answer 2

Answer:

By trial and error method:

(a) 3+x =8 ----(i)

We put x = 5 in eq (i)

3 + 5 = 8

8 = 8

It is true

Hence x= 5 is a solution.

b) 3× x/ 2 =3---(ii)

we put x = 2 in eq (ii), we get

3× 2/2= 3

3 × 1= 3

3 = 3

It is also true

Hence , x = 2 is the another solution of given question.
