What is x when 19 divided by x equals 2?

To find the answer, just divide the dividend by the quotient: 19 ÷ 2 = 9.5

To prove this, let's compute 19 divided by 9.5: $\frac{19}{9.5} = 2$

How does it work?

Asking what the value of x could be when 19 divided by x gives a result of 2, is equivalent to solving the following equation:

$\frac{19}{x} = 2$

Multiply both sides by x: $\frac{19 x}{x} = 2 x$
$\frac{19 x}{x}$ is equivalent to $\frac{x}{x} \times 19$ , which simplifies to $1 \times 19$ (or just $19$ ).
Thus, the equation becomes: $19 = 2 x$
To find x, divide both sides by 2: $\frac{19}{2} = \frac{2 x}{2}$
Which gives, after simplification: $9.5 = x$ (or $x = 9.5$ )

So, if the dividend is 19 and the quotient is 2, the divisor is 9.5.
