What is x when 84 divided by x equals 23?

To find the answer, just divide the dividend by the quotient: 84 ÷ 23 = 3.6521739130435

To prove this, let's compute 84 divided by 3.6521739130435: $\frac{84}{3.6521739130435} = 23$

How does it work?

Asking what the value of x could be when 84 divided by x gives a result of 23, is equivalent to solving the following equation:

$\frac{84}{x} = 23$

Multiply both sides by x: $\frac{84 x}{x} = 23 x$
$\frac{84 x}{x}$ is equivalent to $\frac{x}{x} \times 84$ , which simplifies to $1 \times 84$ (or just $84$ ).
Thus, the equation becomes: $84 = 23 x$
To find x, divide both sides by 23: $\frac{84}{23} = \frac{23 x}{23}$
Which gives, after simplification: $3.6521739130435 = x$ (or $x = 3.6521739130435$ )

So, if the dividend is 84 and the quotient is 23, the divisor is 3.6521739130435.
