The solution
Detail solution
Given the equation:
$$10 \frac{12}{x} = 13$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
so we get the equation
$$- \frac{x}{120} = - \frac{1}{13}$$
$$- \frac{x}{120} = - \frac{1}{13}$$
Divide both parts of the equation by -1/120
We get the answer: x = 120/13
$$10 \frac{12}{x} = 13$$
Use proportions rule:
From a1/b1 = a2/b2 should a1*b2 = a2*b1,
In this case
a1 = 1
b1 = -1/13
a2 = 1
b2 = -x/120
so we get the equation
$$- \frac{x}{120} = - \frac{1}{13}$$
$$- \frac{x}{120} = - \frac{1}{13}$$
Divide both parts of the equation by -1/120
x = -1/13 / (-1/120)
We get the answer: x = 120/13
