The solution
Detail solution
Given the equation:
$$85 + 68 \cdot \frac{1}{x} 15 = 145$$
Use proportions rule:
From $\frac{a_1}{b1} = \frac{a_2}{b_2}$ should $a_1*b_2 = a_2*b_1$,
In this case
so we get the equation
$$1 \left(- \frac{x}{1020}\right) = 1 \left(- \frac{1}{60}\right)$$
$$- \frac{x}{1020} = - \frac{1}{60}$$
Divide both parts of the equation by -1/1020
We get the answer: x = 17
$$85 + 68 \cdot \frac{1}{x} 15 = 145$$
Use proportions rule:
From $\frac{a_1}{b1} = \frac{a_2}{b_2}$ should $a_1*b_2 = a_2*b_1$,
In this case
a1 = 1
b1 = -1/60
a2 = 1
b2 = -x/1020
so we get the equation
$$1 \left(- \frac{x}{1020}\right) = 1 \left(- \frac{1}{60}\right)$$
$$- \frac{x}{1020} = - \frac{1}{60}$$
Divide both parts of the equation by -1/1020
x = -1/60 / (-1/1020)
We get the answer: x = 17
