Question

Verify that a=2 is not the solution to 8 a -4 =0

Answer 1

Step-by-step explanation:

a = 2

8a - 4 = 0

8a = 4

8 × 2 = 4

16 = 4

{ LHS is not equal to RHS}

Therefore, a = 2 is not a solution for the given equation.

----------------

The real solution for 'a' would be :

a = 1/2.

Answer 2

Answer:

Given a=8 , it's mean that on putting the value of a in eqn 8a-4 becomes =0 so now put value

Step-by-step explanation:

8a-4=0

8×2-4=0

8does not =0

hence a=2 is not the solution of eqn 8a-4
