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. $3x-1=3$

Answer 1

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

$x=0$
$\text{3x = 3}\times \text{0 (multiplying both sides by 3)}$
$\text{3x - 1 = 0 - 1 (subtracting 1 on both sides)}$
$\text{3x - 1 = -1 is the required equation}.$
