Question

Which of the following equations can be formed starting with x = 0?

विकल्प

• 2x + 1 = –1

• `x/2` + 5 = 7

• 3x – 1 = –1

• 3x – 1 = 1

Answer 1

3x – 1 = –1

Explanation:

We have, x = 0

On multiplying both the sides by 3, we get

3 × x = 3 × 0

⇒ 3x = 0

On adding (–1) both the sides, we get

3x + (–1) = 0 + (–1)

⇒ 3x – 1 = –1
