The solution
Detail solution
Given the equation:
$$- \frac{6}{25 x} = - \frac{3}{8}$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
so we get the equation
$$\frac{25 x}{6} = \frac{8}{3}$$
$$\frac{25 x}{6} = \frac{8}{3}$$
Divide both parts of the equation by 25/6
We get the answer: x = 16/25
$$- \frac{6}{25 x} = - \frac{3}{8}$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 1
b1 = 8/3
a2 = 1
b2 = 25*x/6
so we get the equation
$$\frac{25 x}{6} = \frac{8}{3}$$
$$\frac{25 x}{6} = \frac{8}{3}$$
Divide both parts of the equation by 25/6
x = 8/3 / (25/6)
We get the answer: x = 16/25
