The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -18
We get the answer: x = -4/3
6*(-3*x-9) = -30
Expand brackets in the left part
-6*3*x-6*9 = -30
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -18
x = 24 / (-18)
We get the answer: x = -4/3
