What is x when 86 divided by x equals 17?

To find the answer, just divide the dividend by the quotient: 86 ÷ 17 = 5.0588235294118

To prove this, let's compute 86 divided by 5.0588235294118: $\frac{86}{5.0588235294118} = 17$

How does it work?

Asking what the value of x could be when 86 divided by x gives a result of 17, is equivalent to solving the following equation:

$\frac{86}{x} = 17$

Multiply both sides by x: $\frac{86 x}{x} = 17 x$
$\frac{86 x}{x}$ is equivalent to $\frac{x}{x} \times 86$ , which simplifies to $1 \times 86$ (or just $86$ ).
Thus, the equation becomes: $86 = 17 x$
To find x, divide both sides by 17: $\frac{86}{17} = \frac{17 x}{17}$
Which gives, after simplification: $5.0588235294118 = x$ (or $x = 5.0588235294118$ )

So, if the dividend is 86 and the quotient is 17, the divisor is 5.0588235294118.
