The solution
Detail solution
Given the equation:
$$4 + \frac{1}{3 x} = 0$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
so we get the equation
$$- 3 x = \frac{1}{4}$$
$$- 3 x = \frac{1}{4}$$
Divide both parts of the equation by -3
We get the answer: x = -1/12
$$4 + \frac{1}{3 x} = 0$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 1
b1 = 1/4
a2 = 1
b2 = -3*x
so we get the equation
$$- 3 x = \frac{1}{4}$$
$$- 3 x = \frac{1}{4}$$
Divide both parts of the equation by -3
x = 1/4 / (-3)
We get the answer: x = -1/12
