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:
$$- 69 x = 33$$
Divide both parts of the equation by -69
We get the answer: x = -11/23
(x-8)+(x-19)-71*x = 6
Expand brackets in the left part
x-8+x-19-71*x = 6
Looking for similar summands in the left part:
-27 - 69*x = 6
Move free summands (without x)
from left part to right part, we given:
$$- 69 x = 33$$
Divide both parts of the equation by -69
x = 33 / (-69)
We get the answer: x = -11/23
