$x = 30$ $x = 30$

Explanation:

Let the number be $x$ $x$ so that we have something to use to make an equation.
$\frac{x}{2} - 5 = \frac{x}{3} or \frac{x}{2} - \frac{x}{3} = 5$ $x/2 -5 = x/3 " or " x/2 -x/3 = 5$

$\times 6 : 3 x - 30 = 2 x$ $xx 6:" " 3x - 30 = 2x$

$x = 30$ $x = 30$

Check: $\frac{1}{2} \times 30 = 15$ $1/2 xx 30 = 15$
$\frac{1}{3} \times 30 = 10$ $1/3 xx 30 = 10$

$15 - 10 = 5$ $15-10 = 5$
