Answer 2

It is given that,

• 2a - 4b = 1
• b + 2c = 0
• a = 1/2

We need to find the value of a × b × c.

We know the value of a. So now let's calculate b and c as well.

Firstly, to calculate the value of b, let's put the value of a in the first equation.

➙ 2(1/2) - 4b = 1

➙ 1 - 4b = 1

➙ - 4b = 0

➙ b = 0

Now, to calculate the value of c, we can put the value of b in the second equation.

➙ 0 + 2c = 0

➙ c = 0

Now, we have :

a = 1/2

b = 0

c = 0

So, abc = 1/2 × 0 × 0 = 0.

Hence, the value of a × b × c = 0.
