Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$0 = - 38.4922571428571 x - 842.755371428571$$
Move the summands with the unknown x
from the right part to the left part:
$$38.4922571428571 x = - 4.9737991503207 \cdot 10^{-14} x - 842.755371428571$$
Divide both parts of the equation by 38.4922571428571
We get the answer: x = -21.8941531098277
(258/125)*31*24 = (2.17295*24*31*(18-x))/42
Expand brackets in the left part
258/125*31*24 = (2.17295*24*31*(18-x))/42
Expand brackets in the right part
258/125*31*24 = 2.17295*24*31*+18-x)/42
Looking for similar summands in the right part:
191952/125 = 692.860628571429 - 38.4922571428571*x
Move free summands (without x)
from left part to right part, we given:
$$0 = - 38.4922571428571 x - 842.755371428571$$
Move the summands with the unknown x
from the right part to the left part:
$$38.4922571428571 x = - 4.9737991503207 \cdot 10^{-14} x - 842.755371428571$$
Divide both parts of the equation by 38.4922571428571
x = -842.755371428571 - 4.9737991503207e-14*x / (38.4922571428571)
We get the answer: x = -21.8941531098277
