The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{14} = \frac{27}{14}$$
Divide both parts of the equation by -1/14
We get the answer: x = -27
(x/7)-((3*x-1)/14) = 2
Expand brackets in the left part
x/7-3*x/14+1/14) = 2
Looking for similar summands in the left part:
1/14 - x/14 = 2
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{14} = \frac{27}{14}$$
Divide both parts of the equation by -1/14
x = 27/14 / (-1/14)
We get the answer: x = -27
