What is x when 86 divided by x equals 2?

To find the answer, just divide the dividend by the quotient: 86 ÷ 2 = 43

To prove this, let's compute 86 divided by 43: $\frac{86}{43} = 2$

How does it work?

Asking what the value of x could be when 86 divided by x gives a result of 2, is equivalent to solving the following equation:

$\frac{86}{x} = 2$

Multiply both sides by x: $\frac{86 x}{x} = 2 x$
$\frac{86 x}{x}$ is equivalent to $\frac{x}{x} \times 86$ , which simplifies to $1 \times 86$ (or just $86$ ).
Thus, the equation becomes: $86 = 2 x$
To find x, divide both sides by 2: $\frac{86}{2} = \frac{2 x}{2}$
Which gives, after simplification: $43 = x$ (or $x = 43$ )

So, if the dividend is 86 and the quotient is 2, the divisor is 43.
