What is x when 58 divided by x equals 7?

To find the answer, just divide the dividend by the quotient: 58 ÷ 7 = 8.2857142857143

To prove this, let's compute 58 divided by 8.2857142857143: $\frac{58}{8.2857142857143} = 7$

How does it work?

Asking what the value of x could be when 58 divided by x gives a result of 7, is equivalent to solving the following equation:

$\frac{58}{x} = 7$

Multiply both sides by x: $\frac{58 x}{x} = 7 x$
$\frac{58 x}{x}$ is equivalent to $\frac{x}{x} \times 58$ , which simplifies to $1 \times 58$ (or just $58$ ).
Thus, the equation becomes: $58 = 7 x$
To find x, divide both sides by 7: $\frac{58}{7} = \frac{7 x}{7}$
Which gives, after simplification: $8.2857142857143 = x$ (or $x = 8.2857142857143$ )

So, if the dividend is 58 and the quotient is 7, the divisor is 8.2857142857143.
