Question

$3 x - 9 = 0$
$\Rightarrow 3 x = 9 + 0$
$\Rightarrow 3 x = 9$
$\Rightarrow x = 9 \times 3$
The error in solving linear equation $3 x - 9 = 0$ is

x = 9 \times 3

Solution

The correct option is A $x = 9 \times 3$
In the steps below,

$3 x - 9 = 0$
$\Rightarrow 3 x = 9 + 0$
$\Rightarrow 3 x = 9$
$\Rightarrow x = 9 \times 3$ ,

$x = 9 \times 3$ is incorrect .

It is supposed to be $x = \frac{9}{3} = 3$
