The solution
Detail solution
Given the equation:
$$\frac{12}{x} = 3$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
so we get the equation
$$- \frac{x}{12} = - \frac{1}{3}$$
$$- \frac{x}{12} = - \frac{1}{3}$$
Divide both parts of the equation by -1/12
We get the answer: x = 4
$$\frac{12}{x} = 3$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 1
b1 = -1/3
a2 = 1
b2 = -x/12
so we get the equation
$$- \frac{x}{12} = - \frac{1}{3}$$
$$- \frac{x}{12} = - \frac{1}{3}$$
Divide both parts of the equation by -1/12
x = -1/3 / (-1/12)
We get the answer: x = 4
