Question
Which of the following equations can be formed starting with x = 0?
Options
2x + 1 = –1
`x/2` + 5 = 7
3x – 1 = –1
3x – 1 = 1
Solution
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
