Answer:

x = 8,

Explanation:

$\displaystyle (4)/(x) = (5)/(10)$ .

$x \\e 0$ for it is a denominator. Multiply both sides with the product of the two denominators:
$10\;x$ :

$\displaystyle (4)/(x)\cdot (10\; x) = (5)/(10)\cdot (10\;x)$ .

$40 = 5\; x$ .

Multiply both sides by one over the coefficient of x:

$\displaystyle (1)/(5) * 40 = (1)/(5)* 5\; x$ .

x = 8 .
