Question

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

• A. 2x + 1 = -1
• B. $\frac{x}{2}+5=7$
• C. 3x - 1 = - 1
• D. 3x - 1 = 1

Answer 1

The correct option is C 3x - 1 = - 1

We have, x = 0
On multiplying both the sides by 3, we get
$3\times x=3\times 0$
$\Rightarrow 3x=0$
On adding (-1) both the sides, we get
3x + (-1) = 0 + (-1)
$\Rightarrow 3x-1=-1$
